About NEMA Plugs, Sockets, and Receptacles

Identify your power connector's NEMA type by matching its blades or slots to our diagram.

High-Current Pin-and-Sleeve Connectors

A high current rating makes these connectors suitable for use in industrial machinery and floodlights. Push and twist to join connectors. When mated, they form a vibration-resistant connection to prevent accidental disconnection. The housing is shatter- and crack-resistant rubber so they can withstand rough environments.
