GFCB240 - 40 Amp Circuit Breaker

GFCB240 - 40 Amp Circuit Breaker

The GFCB240 is a 40 Amp, 2-pole plug-on circuit breaker used in electrical panels that accept the GFCB series breaker style. It provides thermal-magnetic protection for overload and short-circuit conditions and includes a common trip design so both poles operate together when the breaker trips. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications.

When you're replacing a breaker, getting the specifications right is the important part. The amperage, voltage rating, pole count, and mounting style all need to match the panel and the circuit being serviced. The GFCB240 plug-on design is made for compatible panels, while the two-pole configuration allows it to be used on circuits that require protection across both legs of a 120/240V supply.
