FXD62B125 - 125Amp Circuit Breaker

FXD62B125 - 125Amp Circuit Breaker

The FXD62B125 is a 125 Amp, 2-pole molded case circuit breaker used in electrical systems that require an FXD/FD frame breaker with a thermal-magnetic trip unit. It is commonly selected for commercial and industrial electrical equipment where maintaining the existing breaker specifications is important. When you're replacing a breaker in an established system, the correct match comes down to more than just amperage — the frame style, pole configuration, voltage rating, interrupting capacity, and trip characteristics all need to align with the original equipment.
