Challenger CE3070 3 Pole Molded Case Circuit Breaker

Challenger CE3070 is a three‑pole molded‑case circuit breaker rated for 70 A at up to 480 V AC, designed to protect three‑phase feeders and branch circuits in commercial and light‑industrial power distribution. As part of Challenger’s CE line, it shares the Series C characteristics and, in Eaton’s current cataloging, aligns with the EHD3070 family, offering an interrupting capacity of 14 kAIC at 480 V. The rugged molded‑case construction supports compact installation and straightforward replacement in compatible Challenger/Eaton panels, with thermal‑magnetic trip action that provides both long‑time and instantaneous overcurrent protection for 3‑phase circuits. Typical applications include protection of motors, transformers, and distribution feeders in facilities operating 480 V three‑phase service, such as warehouses, offices, and light manufacturing floors. This model is commonly cross‑listed with Eaton’s Series C equivalents, helping maintain panel protection ratings and coordination when replacing older Challenger breakers in compatible distribution systems.
