FC34090 - 90 Amp Circuit Breaker

FC34090 - 90 Amp Circuit Breaker

A replacement circuit breaker should match more than just the amperage. Before installing the FC34090, verify the catalog (part) number, breaker type, frame, amperage, number of poles, voltage rating, interrupt rating (A.I.C.), dimensions, and terminal configuration to confirm compatibility with your existing electrical equipment. Taking the time to match these specifications helps maintain the original design of the electrical distribution system and supports a straightforward replacement.
