About Appleton-Powertite Pin-&-Sleeve Devices

A weather-resistant enclosure makes these Appleton-Powertite pin-and-sleeve devices ideal for hazardous environments where there is exposure to chemicals and gases as well as wet environments, such as shipping docks. They are commonly used for equipment such as lighting systems, heaters, compressors, and air conditioners.

Designed to withstand heavy-duty conditions, these receptacles have a safety switch with a watertight IEC receptacle that only accepts IEC plugs. When the switch is in the on position, it prevents the plug from disconnecting.
