Industrial CED3125 3 Pole Bolt On Circuit Breaker

Challenger CED3125 is a 125 A, 240 V, three-pole molded‑case circuit breaker designed for bolt-on (feed‑through) mounting in three‑phase power systems. As part of the CED series, it provides thermal‑magnetic overcurrent protection with a 65 kA interrupting capacity at 240 V, enabling reliable protection for feeders and downstream circuits in panels and switchgear that accept bolt-on devices. The three‑pole configuration protects all three phases of a 3‑phase circuit, making it suitable for distribution panels and similar enclosures with a 125 A maximum load. Its bolt-on/feed-through mounting option supports secure installation in compatible enclosures and facilitates straightforward termination for 3‑conductor per‑phase connections. This model is commonly used to shield feeders and downstream equipment in 3‑phase distribution systems that require a 125 A, 240 V protection device with a 65 kAIC rating.
