FC3100 - 100Amp Circuit Breaker

FC3100 - 100Amp Circuit Breaker

Replacing your molded case circuit breaker is about more than matching the amperage. For a proper replacement, it's important to verify the original breaker's catalog number, breaker type, frame, amperage, pole count, voltage rating, interrupt rating (AIC), dimensions, and terminal configuration.

The breaker features a factory-installed non-interchangeable trip unit, maintaining its calibrated trip characteristics throughout its service life. Rated for operation in ambient temperatures up to 40°C, the FC3100 is well suited for standard commercial and industrial installations. This model also includes load terminals, simplifying installations where they are required.
