Breakers Unlimited GHB3030 Molded Case Circuit Breaker 30A

Product Description

The BREAKERS UNLIMITED GHB3030 is an Eaton Series C complete molded case circuit breaker in the G-frame (GHB) family. It provides fixed thermal and fixed magnetic trip protection in a three-pole configuration rated at 30 amps. Voltage ratings cover 480Y/277 Vac and 125/250 Vdc, and the breaker operates at 50/60 Hz. Licensed electricians and industrial maintenance technicians install this breaker in panelboards and load centers where reliable branch-circuit or feeder protection is required. The molded case construction delivers consistent performance in both commercial and light industrial applications.

The GHB3030 is suited for three-phase branch-circuit protection in commercial buildings, industrial facilities, and similar installations where 480Y/277 Vac distribution systems are used. Its compact G-frame footprint fits panelboards designed for the GHB series. The fixed thermal element responds to sustained overloads, and the fixed magnetic element provides instantaneous response to short-circuit currents, making it a dependable choice for motor loads, lighting circuits, and general-purpose feeders.
