Industrial Three-Phase Plug

The Hubbell HBL4100P7W is a 100A 480V AC watertight pin and sleeve plug built for three-phase, four-wire industrial and commercial power connections. Its non-metallic Zytel 801 nylon housing resists impact and chemical exposure. An IP67 and NEMA 4X rating ensures watertight integrity in wet or corrosive environments. Screw terminals accept 3 AWG to 1/0 AWG conductors with a cable diameter up to 1.065 in.

Suited For Harsh Environments

This plug serves facilities that require reliable three-phase power delivery in wash-down, outdoor or chemically aggressive areas. The gasketed sealing ring and solid one-piece pins maintain contact integrity under vibration and temperature swings from -40°C to +75°C. It is not intended for single-phase residential wiring or for installations that cannot accommodate the stated wire gauge range and cable diameter limits.

100A 480V Three-Phase Rating

The decisive specification is the 100A 480V AC three-phase rating combined with the IP67 watertight enclosure. This defines the plug for heavy-duty industrial circuits where moisture ingress protection and high-current three-phase capacity are both mandatory. Verify that the supply voltage, phase configuration and conductor sizes match these ratings before installation.

Questions about this item

What does the 100 A rating mean when this plug is installed in a three-phase circuit?

It indicates the maximum continuous current the plug can carry at 480 V AC across three phases with a ground conductor, using screw terminals sized for 3 AWG to 1/0 AWG conductors.

Which IEC 60309 interface standard governs this plug, and what voltage configuration does it lock in?

The plug follows IEC 60309-1 for 100 A, 480 V AC, three-phase, four-wire (3P+E) pin-and-sleeve connections, keyed by the red housing to prevent mismating with other voltages.

What cable diameter and mounting clearance does the Zytel 801 nylon body require?

The external cord grip accepts cables up to 1.065 in diameter, and the gasketed sealing ring with IP67 rating fits standard IEC 60309 100 A receptacles without additional mounting hardware.
