FXD62B250L - 250Amp Circuit Breaker

FXD62B250L - 250Amp Circuit Breaker

The Siemens FXD62B250L is a 250 Amp, 2-pole molded case circuit breaker with a fixed thermal-magnetic trip unit and an FD frame. Rated for systems up to 600VAC, it's often used when an existing FD frame breaker needs to be replaced with one that matches the original electrical specifications. If you're replacing a breaker, the amperage is only part of the equation. The frame size, voltage rating, interrupting capacity, and trip characteristics all need to line up with the equipment already in service. That's what makes the catalog number so important.
