Overview
The Pass & Seymour L630-C Turnlok Connector is a heavy-duty locking connector rated for 30 amps at 250 volts, conforming to NEMA L6-30R specifications. Manufactured by Legrand and built for industrial environments, this 2-pole, 3-wire connector delivers reliable, polarized power connections for machine tools, welders, and stationary equipment. The L630-C accommodates 4 AWG wire and is designed for field assembly onto SO-type cables with quick-thread mechanisms.
Key Features
- Brass alloy plug blades and tin-plated Strescon contacts resist heat rise and provide excellent conductivity
- Double-dovetail design prevents cord pull-out forces and ensures secure mechanical retention
- Raised ribs on grip surfaces deliver non-slip turning profiles for safe locking and unlocking
- External cord grips provide visible confirmation of proper and safe cord retention
- Quick-thread assembly screws backed out and ready-to-wire; integral flexible rubber cord grommet seals against oils, water, and chips
- Impact- and corrosion-resistant nylon 6/6 shell with rounded back contour reduces snags on job sites
