Eaton GHB3030 Three-Phase Bolt-On Circuit Breaker

The Eaton GHB3030 is a bolt-on, three-pole circuit breaker rated for 30 amperes, designed for three-phase electrical systems. It operates on 480Y/277V, a common standard for commercial and industrial distribution, and is identified by the model name GHB3030 as part of Eaton’s GHB bolt-on breaker family. This device provides overcurrent protection for three-phase circuits by interrupting current when faults or overloads occur, helping safeguard wiring and connected equipment in installations that use 480Y/277V power. The 3-pole configuration is suitable for protecting three-phase feeders or branch circuits, and the bolt-on construction signals a mounting method for compatible equipment that accepts GHB-series breakers. Key specifications include: 30 A rating, 3-pole, 480Y/277 V three-phase voltage rating.
