FXD62B250 - 250Amp Circuit Breaker

FXD62B250 - 250Amp Circuit Breaker

The Siemens FXD62B250 is a 250 Amp, 2-pole molded case circuit breaker with a fixed thermal-magnetic trip unit and a maximum voltage rating of 600VAC. It belongs to Siemens' FD frame SENTRON family and is a practical choice when you're replacing an existing breaker with the same frame size and electrical ratings. Getting those specifications right matters because it helps the replacement fit the equipment as intended and minimizes the chance of unexpected installation issues.
