Hubbell Incorporated HBL69W49 Watertight Flanged Locking Receptacle L7-30R 30A 277V

Industrial watertight locking receptacle

The Hubbell HBL69W49 is a NEMA L7-30R flanged receptacle rated for 30 amps at 277 volts AC. It provides a 2-pole, 3-wire locking connection designed for industrial environments that demand secure, moisture-proof power distribution. The unit mounts flush with a rectangular flange and accepts conductors from 18 AWG to 8 AWG. It serves maintenance crews and facility engineers who need reliable single-phase service in wet or wash-down areas.

30 A 277 V headroom and limits

The receptacle handles continuous loads up to its 30-amp rating across the 18-to-8 AWG wire range, with nickel-plated brass contacts and stainless-steel hardware maintaining conductivity in harsh conditions. Its operating window spans -40 °F to 140 °F, so it remains functional in extreme cold or heat. The NEMA 3R, 3RX, 4, 4X, 6 and IP69K enclosure ratings confirm protection against directed water jets and temporary submersion, but the device does not supply over-current protection or GFCI functionality.

PBT lid and screw-terminal wiring

A PBT lid and thermoplastic elastomer housing seal the interior against ingress while the screw terminals simplify field termination without special tooling. Nickel-plated brass contacts resist corrosion and the stainless-steel mounting hardware withstands vibration. Compliance with ANSI, NEMA WD-1/WD-6 and UL 498 confirms the construction meets recognised safety benchmarks. Installers who require a different NEMA configuration or a higher amperage rating will need a separate receptacle series.
