FD62B175 - 175Amp Circuit Breaker

FD62B175 - 175Amp Circuit Breaker

Finding the correct circuit breaker replacement starts with the details. The amp rating is one of the first things to check, but it is not the only factor that matters. Voltage rating, number of poles, interrupting capacity, trip characteristics, and terminal configuration all need to match the equipment where the breaker will be installed.

The Siemens FD62B175 is a 175 Amp, two-pole molded case circuit breaker designed for your compatible FD-frame electrical distribution applications. It uses a thermal-magnetic trip unit to provide 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.
