Part numbers for B-frame breaker shunt trip modules
Product Line:
Molded Case Circuit Breakers
Resolution:
• Trips the circuit breaker when the control voltage rises above 70% of its rated voltage (Un)
• For use on 2, 3, and 4 pole breakers
• See here for an installation video
*Operating voltages for the shunt trip are visible through the front cover.
