Hubbell 30A Watertight Twist-Lock Connector

The Hubbell HBL2733SW is a 30 A, 480 V AC locking connector rated IP66 for watertight performance. Its Valox housing resists impact and moisture while the shrouded design protects the brass contacts. Screw terminals accept up to 1.15 in cable diameter for secure three-phase connections.

Suits industrial and outdoor three-phase power needs

This connector fits installations that demand a straight, IP66-rated 30 A locking interface with screw-terminal wiring. It is not for buyers who need a lower amperage rating, a different NEMA configuration, or a non-shrouded body style.

Handles 30 A continuous at 480 V AC three-phase

The 3-pole, 4-wire layout delivers full-rated current within the IP66 enclosure. Headroom ends at the 30 A limit or if the cable exceeds the 1.15 in maximum diameter, requiring a larger-conductor device.

Questions about this item

What cable diameter does the HBL2733SW connector accept?

The connector accepts cables up to 1.15 in. maximum diameter, using screw terminals for a secure connection.

Will the IP66 rating protect the connection if I use it with older non-watertight plugs?

The IP66 watertight seal requires the matching shrouded twist-lock interface; older non-shrouded plugs will not engage the gasket and the rating is not maintained.

How can I confirm the 30 A, 480V AC rating is active after wiring?

Verify the NEMA L16-30R configuration on the housing, check that all four wires are secured in the brass screw terminals, and ensure the press-on cap locks the shroud in place.
