Challenger CE3020 Three-Phase Circuit Breaker

Challenger CE3020 is a three‑phase, 20‑amp molded‑case circuit breaker (MCCB) in the CE series designed for 480V systems. It is a 3‑pole, bolt‑on device with load‑side lug terminals, intended for secure wiring in industrial and commercial distribution gear that accepts Challenger CE family breakers. The CE3020 provides thermal‑magnetic protection with long‑time (overload) and instantaneous (short‑circuit) trip actions, enabling selective protection of feeders and motors in 480V, 3‑phase circuits. It offers a 14 kA interrupting capacity at 480V, allowing rapid fault isolation to minimize damage in fault conditions. This model is designed for use in compatible Challenger panelboards and electrical distribution equipment, delivering reliable protection for 3‑phase circuits at 480V in demanding industrial environments.
