C125 - 25Amp Circuit Breaker

C125 - 25Amp Circuit Breaker

The C125 is a 25 Amp, single-pole circuit breaker designed for use in compatible electrical panels that require a Type C plug-on breaker. It provides overcurrent protection for 120VAC branch circuits by interrupting power when overloads or short circuits occur. While it's a relatively small part of the electrical system, it's one of the components that helps keep everything else protected.

If you're replacing a breaker, chances are you're working with an existing panel and need something that matches what's already there. That's where the C125 is commonly used. Its plug-on design allows it to fit into compatible equipment without changing the panel layout, making it a familiar choice for repairs, maintenance work, and electrical upgrades.

Electrical panels often stay in service for decades, and keeping them operating safely usually comes down to using the right replacement components when needed. The C125 is frequently used on dedicated circuits, equipment loads, HVAC-related controls, and other branch circuits that call for a 25 Amp breaker. With a 10kA interrupting capacity at 120VAC, it provides the level of protection expected for many residential, commercial, and light industrial installations.
