Hubbell Wiring Device-kellems HBLMRGN 400A Male Connector

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBLMRGN is a single-pole male plug connector designed for high-current electrical connections in demanding industrial and commercial environments. Rated at 400 amps and compatible with voltages up to 250 VDC or 600 VAC, this connector uses a threaded stud termination method to ensure a secure, low-resistance connection. It accommodates wire sizes up to 4 AWG. The HBLMRGN carries NEMA ratings of 3R, 4X, and 12, making it suitable for use in wet, corrosive, and dust-laden locations. Electricians and maintenance technicians working on heavy-duty power distribution systems are the primary installers.

This connector is well-suited for industrial facilities, manufacturing plants, and commercial buildings where high-amperage single-pole connections are required. The NEMA 4X rating makes it appropriate for outdoor installations or washdown environments where moisture and corrosive agents are present. Its rugged construction supports use in temporary power setups, generator connections, and permanent feeder applications where reliable disconnection under load is necessary.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before making any terminations at the threaded stud connection. Verify that wire gauge, ampacity, and insulation rating are appropriate for the circuit before installing. Do not exceed the maximum wire size of 4 AWG at the termination point.
