FD62B250L - 250Amp Circuit Breaker

FD62B250L - 250Amp Circuit Breaker

The right circuit breaker replacement is all about matching the details. A 250 amp rating tells you part of the story, but the breaker frame, voltage, pole count, interrupt rating, trip type, and terminal configuration are just as important when matching a breaker to existing electrical equipment.

The Siemens FD62B250L is a 250 Amp, two-pole molded case circuit breaker built for FD-frame electrical distribution equipment. It uses a thermal-magnetic trip unit to provide overload and short-circuit protection for your compatible applications. This breaker is rated for 600 VAC and provides 22 kAIC at 600V and 35 kAIC at 480V interrupting capacity.
