FEATURES


Ark•Gard® 2 receptacle incorporates three spring-loaded slide keys that prevent the receptacle face plate from being rotated until the ENP plug is fully inserted into the receptacle; to make the connection, the ENP plug is fully inserted, and the receptacle face moved inward by pushing the plug forward; the plug is then rotated, closing the circuit; as rotation begins, the plug becomes locked in the receptacle and cannot be accidentally disengaged; in making or breaking the circuit, any resulting electrical arc is confined in the factory sealed chamber

Factory sealed chamber encloses the potential arcing components between two explosionproof threaded joints; these threads are specially coated to guarantee freedom of movement, which ensures on-off action; no additional seals are required

Gasketed screw cap cover design offers superior protection from harsh environments for increased product life

Protected hinged cover design provides 360° protection around cover hinge to reduce damage from dirt and corrosion

Saddle clamp terminals reduce installation and maintenance costs with easy to wire, time-saving terminals

Lockout/tagout hole complies with OSHA lockout/tagout requirements
