Challenger Electrical CM2125 2 Pole Circuit Breaker

Challenger CM2125 is a two-pole molded‑case circuit breaker rated for 125 amps at 240 volts, designed to protect 240 V circuits in Challenger load centers and other compatible panels. The two-pole construction interrupts both hot conductors simultaneously, providing protection for high‑current 240 V circuits such as feeders to subpanels or large appliances in residential or light commercial installations. Built to the durable, modular form factor used by Challenger molded‑case devices, the CM2125 matches the electrical characteristics and mounting footprint of existing 125 A, 2‑pole breakers in suitable panels, making it a straightforward replacement option where a CM/2P 125A breaker is specified. Typical applications include protection of 240 V circuits in homes and small offices that rely on Challenger panel systems, where a reliable 125 A device is required to safeguard wiring and connected equipment. The CM2125’s rugged construction supports long service life under normal operating conditions, delivering predictable disconnection behavior when an overload or fault occurs on a 240 V circuit.
