Features
ENR Receptacles
- 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
- One piece molded gasket seals cover plate and ENP plug when plug is inserted, providing full environmental protection at the receptacle face
- Top-hinged cover design with 45° downward angle provides superior protection in damp, wet, and dirty locations
- Molded-in contact design provides superior interior contact reliability
