Shunt trip
For remote tripping of breaker, a shunt trip device can be added to the MCB. The device opens
the breaker after control voltage is applied.
Undervoltage release
When control voltage drops below approximately 50 percent of rated voltage, the UVR opens the
breaker. The breaker cannot be operated unless proper control voltage is first applied to the UVR coil.
Auxiliary contacts
The auxiliary contacts will signal whether the breaker is in the ON or OFF position.
Bell alarm
The bell alarm includes a set of contacts that will only signal when the breaker has tripped. Typically,
the contacts would be connected to an alarm or bell to signal the operator that an overcurrent
trip has occurred. The bell alarm also includes a test button for testing the alarm contacts without
opening the breaker.
