FD62B070 - 70Amp Circuit Breaker

FD62B070 - 70Amp Circuit Breaker

When you're replacing a circuit breaker, matching the details of the original equipment is what matters most. The amp rating is only one part of the equation. The breaker also needs to match the voltage, pole configuration, interrupting capacity, trip type, and terminal arrangement of the electrical system it is being installed into.

The Siemens FD62B070 is a 70 Amp, two-pole molded case circuit breaker designed for compatible FD-frame applications. It features a thermal-magnetic trip unit that provides overload and short-circuit protection while maintaining the characteristics expected from the original installation. Rated for 600 VAC, this breaker provides an interrupting rating of 22 kAIC at 600 VAC and 35 kAIC at 480 VAC.
