FD62B100 - 100Amp Circuit Breaker

FD62B100 - 100Amp Circuit Breaker

Finding the right breaker replacement is usually about more than matching the amp rating. A 100 amp breaker may look like the right choice, but the voltage rating, pole configuration, interrupting capacity, trip type, and lug setup also need to match the equipment already in service. Checking those details first helps avoid issues when the breaker is installed.

The Siemens FD62B100 is a 100 Amp, two-pole molded case circuit breaker designed for your 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.
