GFCB140 - 40 Amp Circuit Breaker

GFCB140 - 40 Amp Circuit Breaker

The GFCB140 is a 40 Amp, 1-pole plug-on circuit breaker used in electrical panels that accept the GFCB series breaker style. It features thermal-magnetic protection to help guard against overloads and short circuits, along with a common trip design and HACR rating for heating, air conditioning, and refrigeration applications.

Replacing your breaker is usually about finding the correct match. The amp rating, voltage rating, pole count, and mounting style all need to line up with the existing panel and the circuit being serviced. The GFCB140 plug-on connection makes installation simple in matching panels and allows the electrical layout to stay the same without unnecessary changes.
