FXD62B225L - 225Amp Circuit Breaker

FXD62B225L - 225Amp Circuit Breaker

The Siemens FXD62B225L is a 225 Amp, 2-pole molded case circuit breaker from the SENTRON FD family. It features a fixed thermal-magnetic trip unit, a 600VAC rating, and comes with factory-installed line and load lugs (TA1FD350A). If you're replacing an existing FD frame breaker, matching the original electrical ratings and physical configuration is important.

Rated at 22kAIC at 600VAC and 35kAIC at 480VAC, the FXD62B225L is found in many commercial and industrial power distribution systems where dependable circuit protection is required.
