Hazardous-location 20 A receptacle

The Hubbell Killark UGR4-20231QW is a copper-free aluminium receptacle rated for 20 A at 120 V AC, 60 Hz. It provides a NEMA 5-20R configuration with three wires and two poles. A powder-coated finish and stainless-steel screws add corrosion resistance in harsh industrial settings.

Suits wet or corrosive industrial sites.

This unit carries NEMA 3, 7 and 9 ratings, making it appropriate for wet locations and certain hazardous atmospheres where ignition protection is required. Installers needing a standard dry-area outlet without hazardous-area certification should consider a different device.

Feed-thru hub supports continuous conduit runs

A 1/2 in feed-thru hub allows conduit to pass straight through the enclosure, simplifying wiring in extended raceway systems. The copper-free aluminium body and powder coating maintain their protective qualities during prolonged exposure to moisture, chemicals and temperature cycling.
