Challenger CE3030 Three Phase Circuit Breaker

Challenger CE3030 is a three‑pole molded‑case circuit breaker from the CE Series, rated 30 A at 480 V. This bolt‑on device delivers 14 kA interrupting capacity at 480 V and is intended for industrial power distribution where reliable short‑circuit and overload protection are required. It uses a thermal‑magnetic trip mechanism with both long‑time and instantaneous trip functions, and it provides load‑side lug terminals for straightforward wiring. The CE3030 is designed for 3‑phase, 4‑wire systems up to 480 V, making it suitable for protecting feeders and distribution circuits in electrical panels and other equipment. Built for durability in demanding environments, it features a non‑interchangeable trip and bolt‑on mounting to ensure secure installation in compatible enclosures. When service is needed, the unit should be replaced with the same CE3030 model to preserve protective coordination with upstream devices and maintain the specified interrupting and trip characteristics.
