Appleton CPH3034B Electrical Distribution Component

Appleton CPH3034B is a 30‑amp, four‑pole, three‑wire plug in the CPH Series designed for three‑phase power distribution with Appleton JBR/WSR receptacles in industrial or hazardous‑location environments. It is constructed from copperfree aluminum, rated for 125–480 VAC, and supports a 30 A current rating in a 4P/3W configuration. The plug carries NEMA ratings 3, 3R, 4, and 4X and is specified for Class I, Division 1 and 2 (Groups B, C, D); Class II, Division 1 and 2 (Groups F, G); and Class III equipment, aligning with heavy‑duty, weatherproof, and corrosion‑resistant applications. It employs a pressure/wire terminal connection and includes an interlock requirement: the plug must be inserted into the receptacle before the associated switch can be turned on, enhancing safe operation. This model is referenced alongside related variants such as CPH3034BC and is commonly used where JBR receptacles require a compatible CPH plug for reliable, code‑compliant power distribution in demanding environments.
