Circuit Breaker Accessories

Accessories for circuit breakers, including bus bars, trip units, lockouts, shunts, auxiliary contacts, and hardware used to customize panel protection. Trip units, shunt trips, undervoltage releases, auxiliary contacts, bus bars, lockouts and breaker boots extend the function of specific breaker families. Compatibility by series and frame is critical; an accessory designed for one breaker will not necessarily fit another from the same manufacturer. Select accessories from the exact installed breaker part number and control voltage.
