FC3050 - 50Amp Circuit Breaker

FC3050 - 50Amp Circuit Breaker

Replacing a molded case circuit breaker isn't just about matching the amp rating. The FC3050 is a 50 Amp, 3-pole Type FC thermal-magnetic circuit breaker with a factory-installed, non-interchangeable trip unit, so it's important to verify that the replacement matches the original breaker's specifications. Along with the amperage, you'll want to confirm the breaker type, pole configuration, voltage rating, interrupting capacity, and physical dimensions before installation. Those details help ensure the breaker fits properly and continues to provide the protection the electrical system was originally designed for.
