FJ63B110 - 110Amp Circuit Breaker

FJ63B110 - 110Amp Circuit Breaker

The FJ63B110 is a 110 Amp, 3-pole molded case circuit breaker used in electrical distribution equipment designed for the FJ6 frame. It's a practical replacement choice when you're maintaining existing commercial or industrial electrical systems that require the original breaker style and ratings. Matching the correct frame, amperage, and interrupting capacity helps preserve the equipment's original design and avoids unnecessary modifications during maintenance or repairs.
