Sylvania Electric Products SEH-3-C-60 Circuit Breaker

SEH-3-C-60 is a three-pole molded-case circuit breaker from Sylvania’s SEH family, designed for three‑phase distribution in industrial panels and commercial switchgear. The unit is a 60 A device with a voltage rating up to 600 V (nominally used with 480 V three‑phase systems), built to interrupt faults on 3‑pole feeders. It supports a high interrupting capacity of up to 14 kA at 480 V, and it features bolt‑on mounting for secure installation in compatible enclosures. The SEH family is a thermal‑magnetic trip breaker line that provides general protection for 3‑phase circuits, and the SEH-3-C-60 corresponds to the 60‑amp variant within that family. This model has historically been used in older Sylvania/Challenger/GTE panels and similar enclosures designed for SEH breakers, where 480 V three‑phase service is present. In practical terms, the SEH‑3‑C‑60 is chosen to protect mid‑sized 3‑phase feeders and equipment on commercial/industrial power systems, offering dependable fault interruption at standard industrial voltages.
