FJ63B175 - 175Amp Circuit Breaker

FJ63B175 - 175Amp Circuit Breaker

The FJ63B175 is a 175 Amp, 3-pole molded case circuit breaker used in electrical distribution equipment designed for the FJ6 frame. It's a practical choice for maintaining existing commercial and industrial electrical systems where replacing a breaker with the correct frame size, amperage, and interrupting capacity is essential. Whether you're servicing a switchboard, panelboard, or other power distribution equipment, selecting a breaker with the proper electrical characteristics is just as important as finding one that physically fits.
