Hubbell Wiring Device-kellems HBL3431GCB Locking Inlet Plug 30A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL3431GCB is an industrial-grade locking inlet plug rated for 30 amps and 250 volts in a non-NEMA configuration. Built from impact-resistant nylon, it features a self-grounding design with 3 poles and 4 wires. This plug is engineered for demanding industrial electrical installations where a secure, vibration-resistant connection is required. Licensed electricians and industrial maintenance technicians typically install this type of connector in facilities, manufacturing environments, and heavy-duty temporary power applications where standard NEMA configurations are not specified.

This locking plug is suited for three-phase industrial power circuits operating at 250 volts. Its non-NEMA configuration makes it appropriate for specialized equipment connections that require a proprietary or application-specific locking interface. The IP20 ingress protection rating indicates suitability for indoor installations where contact protection from solid objects is required. The cord entry accepts conductor diameters ranging from 0.35 inches to 1.15 inches, accommodating a wide range of industrial cable sizes commonly found in facility power distribution setups.

Compatibility

Designed as an industrial-grade locking inlet plug for use in non-NEMA three-phase power distribution systems requiring a 30A, 250V, 3-pole, 4-wire connection interface.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before beginning any wiring work on this plug. Verify that the selected cord falls within the supported diameter range of 0.35 inches to 1.15 inches before assembly. Do not use this plug in wet or outdoor locations where a higher ingress protection rating is required.
