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

Reliable Power for Heavy-Duty Welding

In a busy welding shop, power interruptions can ruin a weld and damage equipment. The Hubbell HBL2743 Twist-Lock Connector is the professional's choice for building reliable extension cords and power drops for 3-phase welding machines. Rated for 480V and 30 Amps, this female connector body is designed to handle the high power demands of industrial TIG, MIG, and Stick welders.

Prevent Unplanned Disconnects

Standard straight-blade plugs can easily vibrate loose or be kicked out of the wall in a dynamic shop environment. The HBL2743 utilizes a secure locking design—simply plug in and twist to lock. This ensures your welder stays powered even if the cable is tugged or moved, maintaining a stable arc and preventing cold starts or porosity caused by sudden power loss.

Built for the Shop Floor

Welding environments are tough on gear. This connector features a heavy-duty nylon shell that withstands drops, dragging across concrete, and exposure to shop grime. The integrated dust shield helps keep metal dust and debris away from the electrical contacts. Its superior strain relief system grips the cable jacket tightly, preventing the wires from pulling out of the terminals when you drag your power cord across the shop.
