IEC Safe-Break Pin-and-Sleeve Connectors

These connectors meet international standards IEC 309-1 and 309-2, so they’re compatible with other IEC 309 devices. They allow you to connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc. All are approved as switch-rated connectors for branch and motor circuit disconnect switching. Connectors have a ground pin that is included in the number of wires. Rated NEMA 4X, 12, and IP69K, they're protected against corrosion, oil/coolant seepage, washdowns, and high-temperature, high-pressure washdowns.

IEC Pin-and-Sleeve Connectors

These connectors meet international standards IEC 60309-1 and 60309-2, so they’re compatible with other IEC 60309 devices. They have a nonconductive nylon housing so they’re safer to use than components made of metal. Plugs have a notch that must line up with a keyway in sockets and receptacles when mating. All have a ground pin that is included in the number of wires.

Lever-clamp terminals make installation and maintenance quick and convenient. Lower the lever to secure a wire; lift the lever to disconnect it.

IP44 rated connectors protect against damp environments.

IP67 rated connectors protect against dust and submersion.
