HBL2743 - Hubbell HBL2743 Twist-Lock Connector, 30A, 480V, 3-Phase, NEMA L16-30R

Industrial Grade Power Connection

The Hubbell HBL2743 Twist-Lock® Connector Body is a premium electrical component designed for demanding industrial environments. Engineered to the NEMA L16-30R standard, this connector is rated for 30 Amps and 480 Volts AC (3-Phase). It features a 3-pole, 4-wire grounding configuration, making it the standard choice for powering heavy machinery, motors, and industrial distribution panels where secure connections are paramount.

Rugged Construction

Built with Hubbell's renowned Insulgrip® technology, the HBL2743 features a tough nylon housing that resists impact, chemicals, and abrasion. The ribbed design ensures a firm grip even with gloved hands, while the face is color-coded for quick voltage identification. Internally, high-conductivity brass contacts ensure low resistance and minimal heat rise, prolonging the life of your equipment and cables.

Secure & Safe

The defining feature of this connector is its locking mechanism. Once mated with a corresponding male plug (NEMA L16-30P), a simple twist locks the devices together, preventing accidental pull-outs caused by tripping over cords or equipment vibration. The powerful cord grip utilizes an offset jaw design to securely hold cables ranging from 0.35 to 1.15 inches in diameter, providing exceptional strain relief that protects the internal wire terminations.

Installation & Compatibility

Installation is streamlined with clear, transparent terminal chambers that allow for visual verification of wire insertion. The device accepts wire sizes from #16 to #8 AWG. It is fully compatible with all NEMA L16-30P plugs, regardless of manufacturer, though it pairs best with Hubbell's matching plugs for optimal environmental sealing.
