Powerpact H, J, L, M, P and RResolution:
There are two terminals on the UVR and the shunt trip accessories to which you attach the control wires (polarity doesn't matter).
- The shunt trip will trip the circuit breaker if control voltage is applied across the two shunt trip terminals.
- The undervoltage trip will trip the circuit breaker if control voltage is removed from the two undervoltage trip terminals.
Here are links to the instruction bulletins for the shunt trips and undervoltage trips of the Powerpact Breakers
