Eaton CH330 Three-Phase Plug-In Circuit Breaker

The Eaton CH330 is a three‑phase plug‑in circuit breaker rated at 30 A, designed to protect multi‑pole electrical circuits in commercial and light industrial panels. Part of the Eaton CH family, it plugs into compatible panelboards and enclosures for quick replacement or upgrades without extensive rewiring. With three poles, it provides simultaneous interruption on all conductors to safeguard motors, pumps, conveyors, compressors, and other 3‑phase equipment from overloads and short circuits. The plug‑in design supports fast installation and service in systems that use Eaton CH devices, delivering reliable overcurrent protection in modular, space‑efficient form factors. The CH330’s 30‑amp current rating indicates the continuous load current it is intended to carry under normal operation, with tripping acting as protection against fault conditions per the panel’s design. Use this model when a compatible Eaton CH‑series, plug‑in protection solution is required for a 3‑phase distribution circuit.
