20 A 480 V IEC Pin and Sleeve Connector

The Hubbell HBL520C7W is a straight, watertight IEC pin and sleeve connector rated for 20 A at 277/480 V AC three-phase. It accepts cables from 0.33 in to 0.83 in diameter and provides a 10 hp horsepower rating for motor loads. The red, corrosion-resistant housing meets IP68 and IP69K ingress protection for harsh environments.

Verify voltage, phase

Confirm the supply is three-phase 277/480 V AC and that the load does not exceed 20 A or 10 hp. Ensure the cable outer diameter falls between 0.33 in and 0.83 in so the connector seals correctly. This unit is not switch rated, so it cannot serve as a disconnecting means on its own.

IP68 and IP69K housing with spring-loaded cap

The red housing resists corrosion, impact and moisture while the spring-loaded cap seals the face when unmated. A 3.48 in face diameter and straight orientation allow panel or inline mounting in tight spaces. The connector is built for wash-down and submersion conditions typical of industrial and outdoor installations.

Questions about this item

Does the HBL520C7W connector come with a cable, or must I supply my own?

The connector accepts cables from 0.33 in to 0.83 in diameter; the cable itself is not included and must be purchased separately.

Should I select the 20 A 277/480 V AC version or a different amperage for my three-phase motor circuit?

Choose this 20 A, four-pole, five-wire version when your three-phase load requires 277/480 V AC at up to 20 A and 10 hp.

What does the IP68 and IP69K rating mean when the connector is installed on my equipment?

The housing is tested for continuous immersion and high-pressure, high-temperature washdown, so it remains watertight in harsh wet environments.
