Hubbell HBL2730SR Nema L16-30R 30A 480V Locking Receptacle

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL2730SR is a NEMA L16-30R twist-lock receptacle rated for 30 amps at 480 volts AC. It features a 3-pole, 4-wire configuration with a female termination end and a self-grounding design that establishes a ground connection automatically when the device is mounted to a properly grounded metal box. Finished in gray, this receptacle is built for demanding industrial and commercial power distribution applications where secure, vibration-resistant locking connections are required. Licensed electricians and industrial maintenance technicians are the primary installers. The unit weighs 0.5 pounds.

The HBL2730SR is suited for industrial facilities, manufacturing environments, commercial construction, and heavy-duty equipment hookups requiring a 480-volt, 3-phase or high-voltage single-phase locking connection point. Typical applications include motor-driven equipment panels, portable generator outlets, compressor connections, and industrial distribution centers where a twist-lock style receptacle is specified for safety and connection retention. The self-grounding feature makes it well-suited for installations in metal electrical boxes where a dedicated ground wire to the device is not practical.
