Non-NEMA Turn-Lock Connectors

A quarter turn locks these connectors in place to remain secure in high-vibration applications and prevent accidental disconnection. They are not compatible with NEMA configurations.

Styles A, B, C, and D are also known as California Standard plugs, sockets, and receptacles. Plugs have one slot to accept a grounding pin; sockets and receptacles have one grounding pin.
