Hubbell HBL2621SW Locking Plug L6-30P 250V 30A

Product Description

The HUBBELL WIRING DEVICE-KELLEMS HBL2621SW is an industrial-grade locking plug rated for 30 amps at 250 volts in an L6-30P NEMA configuration. Built from thermoplastic elastomer, it offers flexibility and durability in demanding field conditions. The self-grounding design simplifies termination and reduces the chance of grounding errors during installation. With an IP66 ingress protection rating, this plug resists water and dust intrusion, making it suitable for wet or dirty environments. Licensed electricians and industrial maintenance technicians install this component when connecting portable equipment or temporary power runs to matching locking receptacles.

This plug is intended for single-phase industrial applications requiring a secure, twist-lock connection at 250 volts. Its water-tight construction meets NEMA 4, 4X, and 12 enclosure standards, making it appropriate for indoor and outdoor industrial settings, manufacturing floors, construction sites, and equipment rooms. The two-pole, three-wire configuration handles ungrounded 250-volt circuits where a positive mechanical lock is required to prevent accidental disconnection under load.
