Bryant 4730 NEMA Locking Connector, Twist-Lock Receptacle

The Bryant 4730 line of NEMA locking connectors spans catalog numbers 70520NC, 70530NC, 70615NC, 70620NC, 70630NC, 70720NC, 70820NC, 70830NC, 70920NC, and 70930NC, covering NEMA L5 through L9 locking configurations in 15A, 20A, and 30A ratings. Each catalog number is the receptacle ("R") half of its matching locking pair, engineered to mate with the corresponding Bryant locking plug for a twist-lock connection that resists accidental disconnection caused by vibration, tension, or incidental contact. Electrical contractors, facility maintenance teams, and industrial end users specify these Bryant locking connectors for dependable performance in commercial, industrial, and portable power applications where the mechanical lock matters as much as the electrical connection itself. Match the catalog number to the NEMA configuration and amperage already in use to ensure proper mating with existing plugs and connectors.
