Industrial Watertight Receptacle

The Hubbell HBL520R7W is a 20 A IEC pin-and-sleeve receptacle rated for 277/480 V AC three-phase power. Its red thermoplastic housing and IP67 rating suit industrial environments where moisture and dust are present. The spring-loaded cap keeps the contacts sealed when the plug is removed. This device is not for buyers who need a higher amperage rating or a different voltage configuration.

IP67 and NEMA 4X Limits

The IP67 rating protects against temporary immersion and dust ingress, while the NEMA 4X enclosure resists corrosion and directed water jets. The 10 AWG maximum wire size restricts the conductor cross-section you can terminate. The straight orientation and flanged mounting dictate the panel cut-out and wiring direction. Installations requiring angled entries or larger conductors cannot use this receptacle.

Flanged Mount Installation

The single-gang flanged body mounts directly to a panel or box with standard hardware. Five wires connect to the four poles and ground terminal inside the 3.48 in face diameter. The shrouded pins guide the mating plug into correct alignment. Miswiring the three-phase sequence or exceeding the 5 hp motor load rating are the most common errors during commissioning.

Questions about this item

Which version of this 20 A 480 V receptacle should I pick?

The listing shows a single 4-pole, 5-wire, three-phase model rated 277/480 V AC with a spring-loaded cap and straight orientation.

What does the 20 A rating mean once the receptacle is installed?

It supports up to 20 A continuous at 277/480 V AC and a 5 hp motor load, with wiring up to 10 AWG.

How does the IP67 and NEMA 4X rating cap real-world exposure?

The IP67 rating means the receptacle is dust-tight and can withstand temporary immersion, while NEMA 4X adds corrosion resistance for wash-down and outdoor use.
