• Factory sealed chamber in receptacle and connector 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

ENR M4 premier receptacles:

• Gasketed screw cap cover design offers superior protection from harsh environments for increased product life
• Spring-loaded sliding key increases safety by rejecting standard NEMA/EEMAC configuration plugs that could cause an arc in a hazardous area
• Saddle clamp terminals are easy to wire, reducing installation costs and effort
• Lockout/tagout hole complies with OSHA lockout/tagout requirements

ENR M3 value receptacles:

• Top-hinged cover design with 45° downward angle provides superior protection in damp, wet, and dirty locations

ENP plugs:

• Captive set screw design assures ease of installation and reduces likelihood of losing critical components in the field
• Insulator and contact components are now a single-piece assembly
• ENP plugs can be used in non-hazardous areas with standard U-ground NEMA/EEMAC configuration 5 and 6 receptacles, eliminating the need for two separately equipped portable units of the same type; the ENR receptacle will not accept standard NEMA/EEMAC configuration plugs
• Plug body is designed with an internal cord strain relief mechanism and a cable sealing grommet which will accept various cable diameters

ENC connectors:

• Uni-Shell handle body provides a smooth, durable external surface that prevents the connector from getting snagged on equipment or other cables
• Spring-loaded sliding key increases safety by rejecting standard NEMA/EEMAC configuration plugs that could cause an arc in a hazardous area
• Increased environmental reliability with hinged locking cover that provides weather protection in damp, wet and dirty locations; cover stays closed until connection with ENP plug is required
• Improved safety with integral lockout/tagout eliminates risk of operator or contractor plugging in process equipment when conditions are unsafe
• Saddle clamp terminals provide increased safety with easy-to-terminate connection points for reliable conductor terminations
• Increased safety with captive Tri-Lock design: three points of contact prevent pinching of cables that could damage internal conductors or cable jacket; captive screws prevent critical components from getting lost during installation
• Snap-in internal insulator increases safety of personnel with intermediate insulator between conductors and metallic outer shell
