Direct current applications
The S280UC differs from standard miniature
circuit breakers in that the UC versions in-
clude a permanent magnet which aids in the
extinguishing of the arc during medium and
high level faults. It is necessary to observe
the correct polarity and current direction
when connecting the UC breakers. Two ex-
amples of correct connection are shown.
Termination points are marked on all UC
type MCBs, points one (1) and four (4) are
negative and points two (2) and three (3) are
positive.

Miniature circuit breaker
Application guide
Introduction
The circuit breaker plays an important role in providing over-current
protection and a disconnect means in electrical networks. Recent
advancements in circuit breaker technology has increased breaker
performance and protection.
Overload
A slow and small overcurrent situation that causes the ampacity and
temperature of the circuit to gradually increase over time. This type of
event is characterized by a slight increase in the load (ampacity) on the
circuit and is interrupted by the thermal trip unit of the breaker.
Thermal Example
10A
Breaker
Light
15A
The light draws more than 10 amps for
an extended period of time creating a
thermal overload.
Short circuit
A rapid and intense overcurrent situation that causes the ampacity of
the circuit to increase. This type of event is characterized by a dramatic
increase in the load (ampacity) on the circuit and is interrupted by the
magnetic trip unit of the breaker.
Magnetic Example
10A
Breaker
Light
10A
The wire connected between the light and
breaker is cut and shorted to ground
creating a short circuit.
Breaker definition
A breaker is a device designed to isolate a circuit during an overcurrent
event without the use of a fusible element. A breaker is a resettable
protective device that protects against two types of overcurrent
situations; Overload and Short Circuit.

Circuit breaker construction
Thermal / Magnetic trip units definition
ABB Current Limiting Breakers use an electromechanical (Thermal /
Magnetic) trip unit to open the breaker contacts during a overcurrent
event. The thermal trip unit is temperature sensitive and the magnetic
trip unit is current sensitive. Both units act independently and
mechanically with the breaker’s trip mechanism to open the breaker’s
contacts.
Overload protection
The thermal trip unit protects against a continuous overload. The
thermal unit is comprised of a bimetal element located behind the
circuit breaker trip bar and is part of the breaker’s current carrying path.
When there is an overload, the increased current ow heats the bimetal
causing it to bend. As the bimetal bends it pulls the trip bar which
opens the breaker’s contacts.
The time required for the bimetal to bend and trip the breaker varies
inversely with the current. Because of this, the tripping time becomes
quicker as current increases in magnitude.
Overload protection is applicable to any installation, conductor, or
component which can be subjected to low-magnitude but long-
time over-currents. Low-magnitude, long-time over-currents can be
dangerous because they reduce the life of the electrical installation,
conductor, and components and if left unchecked could result in re.
Magnetic trip units (short circuit protection)
The Magnetic trip unit protects against a short circuit. The magnetic
trip unit is comprised of an electromagnet and an armature.
Components of a magnetic trip unit
When there is a short circuit, a high magnitude of current passes
through the coils creating a magnetic eld that attracts the movable
armature towards the xed armature. The hammer trip is pushed
against the movable contact and the contacts are opened. The
opening of the breakers contacts during a short circuit is complete in .5
milli-seconds.

Circuit breaker construction
Arc runners / Arc chutes
The arc runner and arc chute limit and dissipate the arc energy during
the interruption of an overload or short circuit event.
During an overload or short circuit event, the contacts of the breaker
separate and an electrical arc is formed between the contacts through
air. The arc is moved into the arch chute by “running” the arc down the
interior of the breaker along the arc runner. When the arc reaches the
arc chute it is broken into small segmented arcs. The segmented arcs
split the overall energy level into segments less than 25V. Each 25V
segment does not have a high enough energy level to maintain an arc
and all energy is naturally dissipated.
Breaker curves
Thermal Trip Unit (region one)
The rst sloping region of the breaker curve is a graphical
representation of the tripping characteristics of the thermal trip unit.
This portion of the curve is sloped due to the nature of the thermal trip
unit. The trip unit bends to trip the breaker’s trip bar in conjunction with
a rise in amperage (temperature) over time. As the current on the circuit
increases, the temperature rises, the faster the thermal element will trip.
Example using the curve below: If you had a 10A breaker and the circuit
was producing 30 amps of current, the breaker would trip between
2 seconds and 1 minute. In this example you would nd the circuit
current on the bottom of the graph (Multiples of rated current). The rst
line is 10 amps (10 amp breaker x a multiple of one), the second line is
20 amps (10 amp breaker x multiple of 2), and the third line is 30 amps
(10amp breaker x multiple of 3). Next you would trace the vertical 30A
line up until it intersects the red portion of the breaker thermal curve.
If you follow the horizontal lines, on both sides of the red curve, to the
left you will see that the breaker can trip as fast as 2 seconds and no
slower than 1 minute.
Magnetic Trip Unit (region two)
This region of the breaker curve is the instantaneous trip unit. ABB’s
miniature circuit breaker’s instantaneous trip unit interrupts a short
circuit in 2.3 to 2.5 milliseconds. Because of this the curve has no
slope and is graphically represented as a vertical straight line.
Example using the curve above: If you had a 10 amp breaker the
magnetic trip element would interrupt a short circuit between 10 and 30
amps (10 amp breaker x multiple of 2 and 3) in 2.3 to 2.5 milliseconds.
Breaker Contacts (region three)
This region of the curve is the time required for the contacts of the
breaker to begin to separate. The contacts will open in less than .5
milliseconds and is graphically represented by the bottom vertical
portion of the curve.

Circuit breaker current limitation
Current limiting definitions
All ABB Miniature Circuit Breakers are UL tested and certied as current
limiting protective devices. Current limiting circuit breakers provide
a higher level of circuit protection than a typical zero point external
breakers.
UL AC 60Hz cycle
UL denes an AC cycle as the potential energy of the wave form
traveling from Zero-to-Positive amplitude, Positive-to-Zero amplitude,
Zero-to-Negative amplitude, Negative-to-Zero amplitude 60 times in
one second. One cycle is completed every 16.6 milliseconds.
UL breaker current limiting
UL denes breaker current limitation as a breaker that interrupts
and isolates a fault in less than 1/2 of an AC cycle. 1/2 a cycle is
completed in 8.3 milliseconds.
NEC240.2 current limiting
A device that, when interrupting current in its current-limiting range,
reduces the current owing in the faulted circuit to a magnitude
substantially less than that obtainable in the same circuit if the device
were replaced with a solid conductor having comparable impedance.
IEC 60947-2 current limiting circuit breaker
A circuit breaker with sufciently short trip time to prevent the short-
circuit current from reaching the peak value which would otherwise be
reached.
ABB current limiting breakers
ABB current limiting breakers can interrupt and isolate a fault in 1/8 of
an AC cycle. The breaker fault interruption is completed in 2.3 to 2.5
milliseconds.
Zero point extinguishing breakers
A typical zero point extinguishing breaker interrupts a fault and does
not isolate the energy. The breaker allows an arc to be present between
the open contacts until the AC wave form crosses zero. When the
wave form crosses zero, the potential energy is zero and the arc
(fault) naturally extinguishes. The arc could be present for up to 8.3
milliseconds.
Current limiting breakers and electrical networks
Current Limitation
When a short-circuit condition occurs, the “ideal” current limiting circuit
breaker opens before the current waveform can reach its full potential
magnitude which occurs at ¼ cycle (4.17ms). ABB’s current limiting
breakers can interrupt a fault in about ½ cycle or 2.3ms to 2.5ms.
ABB’s current limiting breakers interrupt a short circuit in less than 1/8
cycle and limit the amount of current that can reach a circuit. Limiting
the available current on the circuit provides additional protection
against network, breaker, or bus damage and prevents the tripping of
upstream breakers (selective coordination).
IsqT
The true destructive nature of a short circuit is measured by the time
it is available combined with the peak value of the short circuit. The
IsqT (Amps Squared over Time) value represents the amount of energy
available on a network during a short circuit and is represented by the
shaded area on the graph below.
During a short circuit both magnetic forces and thermal energy
combine to damage devices on the electrical network. The level of
thermal energy and magnetic forces are directly proportional to the
square of the current. The magnetic forces vary as a square of the
peak current available and the thermal energy varies as a square of
the RMS (root mean square) current available. ABB’s current limiting
breakers will limit the let-through energy to a fraction (1/100th) of the
value which is available from the network. By comparison, a Zero
Crossing breaker would let-through approximately 100 times as much
destructive energy as the current limiting circuit breaker
[ (100,000A / 10,000A) squared – 100X].
ABB’s current limiting breakers limit the short circuit current to a
relatively small magnitude in a extremely short time, which dramatically
limits a short circuit’s destructive energy.

Circuit breaker current limitation
Current limiting and zero crossing breakers
During the initial stages of a short circuit a breaker’s contacts open
to interrupt the circuit. After the contacts open an arc forms in the air
between the contacts on both the current limiting and zero crossing
breaker contacts. What distinguishes a current limiting breaker from a
zero crossing breaker is what each breaker does after an arc is formed
between the open contacts.
A current limiting breaker “runs” the arc down the breaker arc runner
into an arc chute that extinguishes the arc.
A zero crossing breaker does not attempt to extinguish the arc. The
breaker is designed to withstand the energy of the arc long enough
for the waveform to cross zero. When the wave form crosses zero the
potential energy is zero and the arc naturally extinguishes itself.
ABB’s current limiting breakers interrupt the arc energy in 2.3ms to
2.5ms (1/8 cycle) and a zero crossing breaker allows the arc to be
present for up to 8.3ms (1/2 cycle). A zero crossing breaker will let
through 100 times as much energy as an ABB current limiting breaker.
Current limiting example
The lab test report below details a 20A S200 series current limiting
breaker interrupting a 28kA fault in 1.7 milliseconds. The total “I
Square T” value is 32.0kA.
Zero crossing example
The test report below details a 20A Zero Point Extinguishing breaker
interrupting a 9kA fault in 9 milliseconds. The total "I Square T" value
is 104.0kA.

Selective coordination and series ratings
IEC 60497-1 selective coordination definition
Coordination between the operating characteristics of two or more
over-current protection devices, so that when an over-current within
established limits occurs, the device designated to operate within those
limits trips whereas the other do not trip.
Example of breaker coordination
When an over-current event occurs at the branch breaker level (CB1),
and the event is within the operating characteristics of the breaker,
then the branch breaker should interrupt the circuit (open) and the
main breaker should remain closed and energized. The chart below
gives a graphical representation of a down stream branch breaker (B
curve) and a main breaker (A curve) with coordination. The separation
between the curves allows the branch breaker to react to the fault and
the main breaker remain closed and energized.
Example of no breaker coordination
Selective breaker coordination is not achieved when there is an
overload event at the branch breaker level (MCB1) and both the branch
breaker and main breaker interrupt the circuit (open). When there is
no breaker coordination several circuits lose power that should remain
operational during and after the overload event. The chart below gives a
graphical representation of a down stream branch breaker (B curve) and
a main breaker (A curve) without coordination. There is no separation
between the curves. The branch breaker will react to a fault and the
main breaker will open and de-energize all circuits down stream.
Problems in coordination occur when the branch breaker allows
the "I Square T" value of the short circuit to rise to a level that is in
the operating range of the up-stream main breaker. Proper breaker
coordination is easier to achieve with the use of current limiting
breakers at the branch level.
Selective coordination and current limiting breakers
Recent improvements in ABB circuit breaker technology has pushed
the performance of breakers to the same level as fuses. The reaction
time and tripping characteristics of current limiting breakers are now on
par with fuses. This allows ABB to provide a high level of coordination
between branch breakers and the main. A current limiting branch
breaker will limit the “I Square T” value well below the level of the
operating range of the up-stream main breaker.
ABB’s current limiting branch breakers can coordinate between the
main breaker up to 35kA.
Selective coordination and zero crossing breakers
Zero crossing breakers do not limit the “I Square T” value. They wait for
the wave form to cross zero and allow a high level of let-through energy
to pass through the system. The “I Square T” value of a zero crossing
breaker is high enough that the main breaker will likely trip during a
short circuit. With zero crossing breakers it is extremely difcult to
coordinate between branch and main breakers.
A typical zero crossing breaker’s coordination level is below 10kA.
There are a few manufactures that have achieved coordination
between a branch zero crossing breaker and the main by slowing the
performance (protection) of the main breaker.

Selective coordination and series ratings
Series ratings –vs- selective coordination
Selective coordination
Selective coordination is achieved when there is a short circuit on a
branch circuit breaker, the branch breaker opens and isolates the fault,
and the main breaker remains closed. The rating is usually a value
above the “stand alone” interrupting rating of the branch breaker and
the “stand alone” rating of the main breaker.
Example:
65kA rated main breaker
10kA rated branch breaker
Coordination between the two breakers up to 35kA
There can be a short circuit on the branch breaker up to 35kA where
the branch will open (CB1) and the main breaker will remain closed.
Although the branch has a 10kA “stand alone” rating both the breakers
work together to limit the available short circuit to allow the branch
(CB1) to isolate the fault.
Series ratings
Series ratings are different from coordination ratings. Unlike
coordination ratings where the branch opens and the main remains
closed, a series rated combination is one where both the branch and
main breakers open and work together to isolate the fault.
The series rating combination of two breakers is equal to the “stand
alone” interrupting value of the main breaker. This is a result of the
main breaker let-through value being lower than the “stand alone”
interrupting value of the branch breaker. During a short circuit the main
breaker will limit the energy to a level that is below the “stand alone”
value of the branch breaker.
Example:
65kA rated main breaker
10kA rated branch breaker
Series combination rating between the two breakers up to 65kA
There can be a short circuit on the branch breaker up to 65kA where
the branch will open and the main breaker will open. Although the
branch breaker (CB1) has a 10kA “stand alone” rating the main breaker
has a let-through value below 10kA. If there is a fault up to 65kA on
the network the main breaker will limit the energy to a value less than
the rating of the branch breaker (CB1). Both breakers will trip (no
coordination) but the network can safely withstand a fault of 65kA.
