FD62B100L - 100Amp Circuit Breaker

FD62B100L - 100Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right is what makes the difference. A 100 amp rating alone does not tell the whole story. The voltage rating, pole configuration, trip type, interrupting capacity, and lug arrangement all need to match the equipment already in place for the replacement to fit the application properly.

The Siemens FD62B100L is a 100 Amp, two-pole molded case circuit breaker built for compatible FD-frame electrical distribution equipment. It features a thermal-magnetic trip unit that provides overload and short-circuit protection while following the requirements of the original system design. Rated for 600 VAC, this breaker provides a 22 kAIC interrupting rating at 600V and 35 kAIC at 480V.
