Westinghouse EL3150R Current Limiter 150A 3Pole 600VAC

The Westinghouse EL3150R Current Limiter is a three-pole, 150 A device that provides instantaneous short-circuit current limiting in three-phase, 600 VAC systems for industrial MCCBs and switchgear. It is designed for installation in motor control centers, switchgear assemblies, and heavy-duty electrical distribution panels to safely curb fault currents, delivering up to 200 kA symmetrical interrupting capacity at 600 VAC. Technical specifications include MCP/HMCP frame compatibility, bolt-on load-end mounting, load-side terminal connections, UL-listed status, and the part number EL3150R; it's commonly used with MCP-series and compatible MCCB frames, with replacements such as Eaton EL3150R, Cutler-Hammer EL3150R, and Westinghouse ELC3150R.
