Challenger CH1025 Molded Case Circuit Breaker

Challenger CH1025 is a 1-pole molded‑case circuit breaker rated for 25 A at 277 V AC, with a 10 kA interrupting capacity, designed to provide reliable overcurrent protection for single‑phase distribution in commercial and light industrial environments. As part of Challenger's CH series, this compact breaker fits panelboards that accept CH‑series devices and features a rugged molded‑case design that supports straightforward wiring and replacement in service panels. It protects branch circuits feeding 277 V loads, such as lighting and general power distribution, helping prevent damage from short circuits or overloads while trips can be reset after the fault is cleared. When selecting this model, verify that your panel is listed for CH‑series molded‑case breakers and that the 10 kAIC rating at 277 V matches your system's available short‑circuit current to ensure proper protection and compliance. Use in accordance with local electrical codes and the panel's listing to ensure proper protection and safe operation.
