FD62B150 - 150Amp Circuit Breaker

FD62B150 - 150Amp Circuit Breaker

Finding the right replacement breaker is usually about getting the details right before the equipment is back online. The amp rating is important, but it is only one piece of the match. The voltage rating, pole configuration, interrupting capacity, trip type, and lug arrangement all need to line up with the electrical equipment already in service.

The Siemens FD62B150 is a 150 Amp, two-pole molded case circuit breaker built 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 installation. Rated for 600 VAC, this breaker provides a 22 kAIC interrupting rating at 600V and 35 kAIC at 480V.
