Appleton™ WSR Interlocked Receptacle
Brand: AppletonWSR 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.
Features- For use where an interlocked disconnect switch is desired to control a Powertite™ receptacle and insertion or removal of plug. Interlock prohibits plug insertion or removal under load. Plug is secured in place by interlock and cannot be withdrawn unless interlock release lever is actuated
- Dead front design: receptacle is not energized until plug is fully inserted and switch is engaged. Unit is equipped with defeatable door interlock which allows emergency access when switch is energized
- An operating mechanism designed to endure at least three times the number of operations required by NEMA and UL standards; modular componentry designed for quick and easy maintenance; and visible blades for an extra measure of safety while the low mass cam allows greater blade operating speed and reduced mechanical wear
