Hubbell HBL2731S Locking Plug L16-30P 480V 30A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL2731S is an industrial-grade locking plug rated for 480 volts and 30 amps in a 3-phase, 4-wire NEMA L16-30P configuration. Built from nylon with a self-grounding design, it is engineered for demanding commercial and industrial electrical installations where vibration or accidental disconnection is a concern. The twist-lock mechanism provides a secure, retained connection at the receptacle. Licensed electricians and industrial maintenance technicians install this plug on power distribution cords, portable equipment, and temporary power setups where 3-phase 480V service is required.

The HBL2731S is suited for industrial facilities, construction job sites, data centers, and commercial buildings where 3-phase 480V power is distributed through portable cord assemblies. It accepts cord diameters from 0.35 inches minimum up to 1.15 inches maximum, covering a broad range of heavy-duty SO and SOOW cord sizes. The IP20 ingress protection rating makes it appropriate for indoor use in dry to moderately protected environments.
