Challenger CE3070L Circuit Breaker 3 Pole 480 V

The Challenger CE3070L is a three-pole, 70A molded case circuit breaker designed for 480 V three-phase systems, and it sits in the Challenger line that is now marketed by Eaton as the Series C family (the equivalent current designation is EHD3070L). This thermal-magnetic device uses fixed thermal and fixed magnetic trip elements to provide both time-delay and instantaneous overcurrent protection, with an interrupt rating of 14 kAIC at 480 Vac (18 kAIC at 240 Vac). It is intended for protection of distribution circuits in industrial panels and motor feeders, and it features line and load terminals for straightforward installation. The CE3070L’s 70 A rating and 3P configuration make it suitable for feeders and equipment in 480 V systems, enabling coordinated protection within a power distribution scheme while guarding against overloads and short circuits.
