Westinghouse GHC3030 Feed-Thru Circuit Breaker

The Westinghouse GHC3030 Feed-Thru Circuit Breaker is a 30 A molded-case device designed for industrial electrical distribution and branch-circuit protection. Rated for 277/480 VAC in a 3-pole, 3‑phase configuration, it employs thermal-magnetic protection to guard against overcurrent and short circuits while enabling feed-through power distribution in panels, switchboards, MCCs, and switchgear. As part of the GHC series, this feed-through breaker is intended for panel- or switchboard-mounted installations in applications such as motor control centers, HVAC infrastructure, conveyors, and automated industrial equipment operating on 277/480 VAC networks at 50/60 Hz. Typical installations include MCCs, switchgear, and industrial control panels, with common replacements to maintain compatibility including Eaton GHC3030, Siemens HGB3030, and Square D EDB34030.
