Hubbell Circuit-Lock® pin and sleeve mechanical interlocks are a revolutionary design that incorporates a disconnect switch and pin and sleeve receptacle in a compact non-metallic unit. These devices offer maximum safety by preventing users from mating or breaking a circuit under load. Hubbell interlock mechanism detects the presence of a plug and prevents it from being removed when the switch is in the ON position. It features a high visibility red handle that can be locked to meet OSHA lockout/tagout regulations and the enclosure door can be locked to prevent unauthorized access. The rugged, corrosion resistant type 4X Valox® enclosure features adjustable mounting feet for flexible installation, while the receptacle's spring loaded cover with gasket is dust tight and provides a watertight seal when turned and locked.
