FD62B175L - 175Amp Circuit Breaker

FD62B175L - 175Amp Circuit Breaker

The right circuit breaker replacement is about more than finding the same amp rating. A proper match also depends on the breaker frame, voltage rating, number of poles, interrupting capacity, trip type, and terminal configuration. Checking those details helps you ensure the breaker fits the electrical equipment it is being used with.

The Siemens FD62B175L is a 175 Amp, two-pole molded case circuit breaker designed for FD-frame electrical distribution applications. It features a thermal-magnetic trip unit that provides overload and short-circuit protection for compatible systems. With a 600 VAC rating, this breaker is rated for 22 kAIC at 600V and 35 kAIC at 480V.
