4.3.2 Undervoltage Trip 
All HV6CS breakers are furnished with an undervoltage trip device. The Undervoltage trip device 
operates to trip the circuit breaker OFF unless 120VAC control power is present at the terminals of 
the UV (TC4) trip coil. 
When the circuit breakers are shipped, the Undervoltage trip device is defeated by a factory 
installed plug (Fig. 30). If this plug is left in place, the circuit breaker will operate normally without 
power applied to the UV coil. Removing this plug (Fig. 31) activates the undervoltage trip function.
