About NEMA Plugs, Sockets, and Receptacles

Safe-Break Pin-and-Sleeve Connectors
Connect and disconnect with the power on—spring-loaded contacts open like a switch when separating the connectors, preventing an electrical arc. These connectors are approved as switch-rated connectors for branch circuit and motor circuit disconnect switching. When mated, they form a NEMA 4X rated connection that resists corrosion and protects against washdowns. A ground pin is included in the number of wires.
Receptacles include a junction box with a conduit entry hub.
Finger drawplates (sold separately) create a grip around plugs and sockets or receptacles, making it easier to pull them together tightly when mating.

Hazardous Location Safe-Break Pin-and-Sleeve Connectors
Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They are CSA certified for Class I, Division 2, Groups A, B, C, and D; and Class II, Division 2, Groups F and G. All have a chamber that withstands the pressure of an internal ignition—isolating it from spreading to the surrounding environment. They're rated IP66 and IP67 for protection from washdowns and temporary submersion.
Finger drawplates (sold separately) create a grip around plugs and sockets or receptacles, making it easier to pull them together tightly when mating.

Corrosion-Resistant Pin-and-Sleeve Connectors
When used together, connectors maintain a watertight and corrosion-resistant NEMA 4X connection. All meet UL 1686 and are fully interchangeable with other UL 1686 configured and listed devices.
3W4P (three wire four pole) connectors have a ground pin that is included in the number of poles. They are marked 3W4P.
Receptacles include a mounting box with a conduit entry hub.
