Auxiliary Switch

Auxiliary Switch

The Auxiliary Switch provides circuit breaker con-

a

tact status information by monitoring the position
of the molded cross bar which contains the mov-

b

ing contact arms. The auxiliary switch is used for

tion, and consists of one or two SPDT switches housed in a
plug-in module. Each SPDT switch has one “a” and one “b”
contact. When the circuit breaker contacts are open, the “a”
contact is open and the “b” contact is closed.

Low Energy Shunt Trip

Low Energy Shunt Trip
devices are designed to
operate from low energy

UV

output signals from dedi­cated current sensors typi-

fault protection schemes. However,
with a proper control voltage source,
they may be applied in place of
conventional trip devices for special
applications. Flux paths surrounding
permanent magnets used in the shunt
trip assembly hold a charged spring
poised in readiness to operate the
circuit breaker trip mechanism.

Low Energy Shunt Trip

When a 100 microfarad capacitor
charged to 28 Vdc is discharged
through the shunt trip coil, the result­ant flux opposes the permanent mag­net flux field, which releases the
stored energy in the spring to trip the
circuit breaker. As the circuit breaker
resets, the shunt trip reset arm is actu­ated by the circuit breaker handle,
resetting the shunt trip. The plug-in
module is mounted in retaining slots
in the top of the trip unit. Coil is inter­mittent-rated only. Cutoff provisions
required in control circuit.

Undervoltage Release Mechanism

Undervoltage Release
Mechanism

The Undervoltage Release
Mechanism monitors a

UV

voltage (typically a line
voltage) and trips the cir-

age falls to between 70 and 35 percent
of the solenoid coil rating.

The undervoltage release mechanism
consists of a continuous rated sole­noid with a plunger and tripping lever
mounted in a plug-in module. The tab
on the tripping lever resets the under­voltage release mechanism when
normal voltage has been restored and
the circuit breaker handle is moved to
the reset (or OFF) position. With less
than pickup voltage applied to the
undervoltage release mechanism, the
circuit breaker contacts will not touch
when a closing operation is attempted.

Note: Undervoltage release mechanism
accessories are not designed for, and
should not be used as, circuit interlocks.

Ordering Information

Select handle reset undervoltage
release mechanism catalog number
for the voltage within the indicated
voltage range. Undervoltage release
mechanism coils are designed to be
applied at specific ac or dc voltages
within the voltage range shown on
applicable circuit breaker accessory
nameplates.
