Zone 2 Hazardous Location Plugs and Receptacles

MELTRIC Zone 2 Hazardous Location plugs and receptacles are CSA/CUS listed for use in Class 1 Zone 2 and Class 1 Division 2 hazardous locations, making them suitable for use in areas where an explosive gaseous atmosphere may exist under abnormal conditions. The listing covers all the gases in Groups A, B, C, and D, with a temperature rating of T6.

Zone 2 Hazardous Location plugs and receptacles deliver safe, reliable connections for motors, pumps, mobile equipment, generators, air handling equipment, portable skids, and more.

They are commonly utilized at:

  • Mining and Extraction Facilities
  • Chemical Plants
  • Oil and Gas Facilities
  • Wastewater Facilities
  • Aircraft Hangers and Airports

MELTRIC Zone 2 plugs and receptacles use spring-loaded, silver-nickel butt contacts that provide excellent conductivity, corrosion resistance, and optimal contact pressure, resulting in superior performance that is maintained for thousands of operations.

Zone 2 devices are not meant for current interruption and include safety features to prevent accidental disconnection. An Allen Head screw-type locking pawl is used to secure the plug and receptacle in the mated position. This prevents accidental disconnection under load. It can also be used to lock the receptacle lid closed.

For added security, a lockout hole is provided on the receptacle pawl. Users can insert a 5/16” diameter lock or locking pin through the lockout hole to padlock the plug and receptacle in the connected position, or to lock the receptacle lid in the closed position.

MELTRIC manufactures a large selection of Zone 2 Hazardous Location plugs and receptacles. AC rated devices are available for applications up to 250 amps and 600 volts; add up to 6 auxiliary contacts for control or monitoring circuits. DS and DSN Series devices are available with non-load break horsepower ratings up to 100 hp. DC devices are available for applications up to 200 amps and 250 volts.

MELTRIC Zone 2 Hazardous Location devices are rated Type 4X and achieve this protection automatically upon connection of the plug and receptacle, making them ideal for installation in wet, dirty environments. Their rugged, impact-resistant metal or poly casings stand up to harsh weather, corrosive environments, and tough applications.

A variety of handles, boxes, mounting angles, and accessories allow Zone 2 plugs and receptacles to be installed in traditional wallbox mounted, in-line, panel mounted, direct motor mount, and other configurations. This makes it easy to insert a plug and play connection wherever it is beneficial.
