Watertight Locking Connector

The Hubbell HBL2513SW is a 20 A watertight locking connector built for three-phase 120/208 V AC circuits. Its IP66-rated Valox housing resists impact and moisture, making it suitable for industrial and outdoor power connections where reliability matters.

Capacity and headroom

Rated at 20 A with a 4-pole, 5-wire L21-20R configuration, it handles standard three-phase loads up to its current limit. The screw terminals accept cables up to 1.15 in. diameter, so thicker conductors or longer runs beyond that size will not fit.

Bundled accessories

A press-on cap is included to seal the connector when not in use, preserving the IP66 rating against water and debris. Brass contacts and the shrouded twist-lock design maintain secure mating cycles without extra parts.

Questions about this item

Will the HBL2513SW fit the existing L21-20R receptacles in my three-phase panel?

Yes, the connector uses the NEMA L21-20R configuration with four poles and five wires, matching standard 20 A three-phase receptacles rated 120/208V AC.

How can I verify the IP66 seal is intact after wiring the screw terminals?

Press the shrouded press-on cap firmly until it clicks; the impact-modified PBT housing and brass contacts maintain a watertight, moisture-resistant barrier when the cap is fully seated.

Does the box include a cable gland for 1.15 in. diameter cable or must I supply one?

The connector accepts cable up to 1.15 in. through its integral screw-terminal wiring chamber; no separate gland is included, so purchase a compatible strain-relief fitting if required.
