OPERATION

MANUAL OPENING:

1.Push the trip lever in the direction of the arrow (Fig. 27).

2.The On-Off indicator changes to OFF (green).

ELECTRICAL OPERATION

The flow chart shown in Fig. 30 illustrates the sequence of electrical operation.

Refer to the schematic shown in Fig. 31 for determining external control circuit connections to the circuit breaker.

UNDERVOLTAGE TRIP

All HV6FS drawout circuit breakers are furnished

with an undervoltage trip device. The Fig. 27 Manually Opening Breaker undervoltage trip device operates to trip the

circuit breaker OFF unless 120VAC control power is present at the terminals of relay UV.

When the circuit breakers are shipped, the undervoltage trip device is defeated by a factory- installed plug (Fig. 28). If this plug is left in place, the circuit breaker will operate normally without power applied to relay UV. Removing this plug (Fig. 29) activates the undervoltage trip function.
