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 
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.
