Overview of trip units
On TD125U (Q) to TS800U (Q) circuit breakers,
the thermal-magnetic is built in trip units.
Some models of the TD&TS series circuit
breakers are UL Listed to be applied at up to
100% of their current rating. Because of the
additional heat generated, the use of speciallydesigned enclosures and 90°C rated wire and
the wire size are required when applying circuit
breakers at 100% of continuous current rating.
Markings on the circuit breaker indicate the
minimum enclosure size and ventilation
required. The 90°C wire size shall be based on
the ampacity of the 75°C wire as indicated on
UL489. Circuit breakers with 100% rating can
also be used in applications requiring only 80%
continuous loading.

Function
Protection of power distribution
�Overload protection: Thermal protection with
a fixed or adjustable threshold
�Short-circuit protection: Magnetic protection
with a fixed or adjustable pick-up
Operation
Trip bar
ATU
Bimetal
Armature
Thermal magnetic types
�Time-Delay operation
An overcurrent heats and warps the bimetal to actuate the
trip bar by the bimetal characteristic.
�Instantaneous operation
If the overcurrent is excessive, the armature is attracted
and the trip bar actuated by electromagnetic force.

The following devices are installed into all TD &
TS circuit breakers regardless of frame size.
And, the electrical auxiliaries can be easily
installed in the accessory compartment of the
circuit breakers which is cassette type.
Undervoltage release, UVT
The undervoltage release automatically opens
a circuit breaker when voltage drops to a value
ranging between 35% to 70% of the line
voltage. The operation is instantaneous, and
after tripping, the circuit breaker cannot be reclosed again until the voltage returns to 85% of
line voltage.
UVT
Continuously energized, the undervoltage
release must be operating before the circuit
breaker can be closed. The undervoltage
release can be easily installed in the left
accessory compartment of the Susol TD and
TS circuit-breakers.

Alarm switch (AL)
Alarm switches offer provisions for immediate
audio or visual indication of a tripped breaker
due to overload, short circuit, shunt trip, or
undervoltage release conditions.
They are particularly useful in automated
plants where operators must be signaled about
changes in the electrical distribution system.
common connection.
One is open and the other closed when the
circuit breaker is open, and vice-versa.
This switch features a closed contact when the
circuit breaker is tripped automatically. In other
words, this switch does not function when the
breaker is operated manually.
Its contact is open when the circuit breaker is
reset.

Fixed mounting
Susol TD and TS circuit-breakers can be
directly connected to the mounting plate.
If busbars or terminals are used to connect the
TD125U (Q)
circuit breaker on the back of the mounting
plate, the appropriate safety clearances must
be observed.

Safety clearance
When a short circuit interruption occur, high
temperatures pressures are present in and
above the arc chambers of the circuit-breaker.
In order to allow the pressure to be distributed
and to prevent fire and arcing or short-circuit
currents, safety clearances are required.
When installing a circuit breaker, safety
clearances must be kept between the breaker
and panels, bars and other protection devices
installed nearby. These safety clearances are
depend on the ultimate breaking capacity and
are defined by tests carried out in accordance
with standard UL489.
