Hubbell Wiring Device-kellems HBL7764C Locking Connector 50A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL7764C is an industrial-grade locking connector inlet rated at 50 amps with a 3-pole, 4-wire configuration. Built from impact-resistant nylon with a self-grounding design, this inlet is engineered for demanding power distribution applications where a secure, vibration-resistant connection is required. The non-NEMA locking interface provides a positive mechanical lock that resists accidental disconnection under load. At a weight of 1.05 pounds, it is compact enough for panel or enclosure mounting in tight installations. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This connector inlet is suited for single-phase industrial power distribution in commercial and industrial facilities. Typical applications include portable equipment connections, temporary power feeds, generator hookups, and fixed panel installations where high-amperage locking connectors are specified. The IP20 ingress protection rating makes it appropriate for indoor and protected outdoor enclosures. Its black and white color scheme allows for clear phase identification in multi-circuit installations.
