Challenger SEH-3-C-70 U Molded Case Circuit Breaker

The Challenger SEH-3-C-70 U is a three-pole molded-case circuit breaker rated for 70 A at up to 480 V, part of Challenger’s SEH family for industrial power protection. It delivers a 14 kA short-circuit current rating at 480 V, making it suitable for protecting 3‑phase feeders and branch circuits in commercial and industrial power-distribution panels that operate on 480 VAC. The SEH-3-C-70 U is designed for use in 3‑phase systems and belongs to Challenger’s legacy molded-case breaker line; in supplier catalogs it is commonly listed as SEH3C070. This model provides overcurrent protection by interrupting fault currents within the equipment it serves, helping prevent damage to downstream wiring and devices in demanding 480 VAC installations. Typical applications include motor feeders and distribution panel boards in facilities with 480 V three‑phase power where reliable 70‑amp protection is required.
