UPR Series 32 Amp Plugs and Sockets are compact, lightweight, strong and corrosion resistant. They are used with portable or stationery electrical equipment in corrosive atmospheres and in Zone 1 and 2 and 21 and 22 installations. The UPR is designed with a mechanical interlock to insure disengagement cannot occur while energized. The same plug used in hazardous locations can also be safely used with interlocking non-hazardous location receptacles.

U-Line™ N1 and N2 Series 20 Amp Plugs and Receptacles feature a nonmetallic Intraground™ enclosure that provides explosionproof protection while withstanding the most extreme corrosive environments. The silicone gasket prevents entrance of moisture without interfering with the venting of cooled hazardous gases and vapors. An embedded aluminum grounding grid provides a complete grounding system with no need for field work and no extra grounding wires or parts.

Powertite™ Series Plugs, Connectors and Receptacles use our versatile pin and sleeve design to provide safe, reliable power for any type of heavy duty equipment, fixed or portable. Available in 30, 60, 100, 150, 200 and 400 Amp designs, they feature widely spaced contacts recessed within an internal arc snuffing chamber, insulating blocks, positive polarization and a durable neoprene sealing bushing. Shell only or shell plus extra pole grounding provides safe, #8221;make first, break last#8221; grounding.

WSRD Interlocked Receptacles are designed to prevent electrical arcing when fixed or portable heavy duty equipment is used in adverse environments. Available in 30, 60 and 100 Amp designs, these metallic receptacles feature either a fused or non-fused disconnect and mechanical interlock that prevents plug removal under load. With a plug engaged and the switch in the ON position, the plug can't be removed. With the switch turned OFF and the plug removed, the receptacle can't be energized.
