Hazardous Duty Plug and Receptacle

DXN Series
The DXN is unique in that it is a hazardous duty plug and receptacle that allows users to make and break under load. It is the ideal plug and receptacle choice for Class I Div II locations.
 
The NEMA 4X and IP67 watertight seal for the DXN series is automatically achieved as soon as the contacts are closed. Each device is made of self extinguishing non-static glass reinforced polyester (PBT) material that offers outstanding resistance to mechanical abuse and chemicals.

DXN products are available in 20, 30 and 60 amp sizes at 480V and for applications where additional control circuits are required, units are also available with two pilot contacts.
Hazardous Duty Certifications

CSA

   • Class I – Indicates suitability for use in applications where flammable Gases, Vapors, or ;Mists may be present.

   • Division 2 – Indicates suitability for use where exposure to the hazard occurs under abnormal conditions.

   • GR A,B,C,D – Indicates suitability for use in areas that may contain Acetylene, Hydrogen, Ethylene, or Propane.

 
   Class II Division 2 Gr E,F,G
   • Class II – Indicates suitability for use in applications where dust may occur.

   • Division 2 – Indicates suitability for use where hazard exposure occurs under abnormal conditions.

   • GR E,F,G – Indicates suitability for use in areas where Magnesium, Coal or Grain dust may occur.

ATEX
   II 2 G/D DUST T85°C EEx ed IIC T6 LCIE 99 ATEX 6027 X
   • II – Indicates suitability for installation in surface applications (as opposed to underground mine applications).

   • 2 – Indicates suitability for use where a high level of protection is required and where the presence of an explosive atmosphere is likely to occur.

   • G/D – Indicates suitability for installation in areas that may contain flammable gases, vapors/mists, or dusts.

   • T85°C – Indicates a maximum surface temperature of the product of 85°C, at 40°C ambient. The temperature class is T6.

   • EEx ed – Indicates that explosion protection is provided with (e) increased safety in the conductor termination area, and (d) explosion proof chambers for making and breaking the current that can withstand the pressure of internal ignition and that prevent arcs, flame or other ignition events from being communicated to the surrounding atmospere.

   • IIC – Indicates suitability for installation in areas where exposure to any type of gas, including the most dangerous subdivision C gases may occur.

   • LCIE 99 ATEX 6027 X – Indicates that the DXN’s ATEX certification was approved by LCIE Laboratory in 1999.
*DXN1 and DXN3 sizes only. DXN6 CSA listings expected soon. Consult factory.

DX Series

Meltric’s DX Series plugs and receptacles are heavy-duty metallic devices that are safe for use in hazardous environments.  They are available in 20, 30, 60 and 100A sizes.  Each device is EEx ed IIC T6 rated to CENELEC standards EN50014/18/19 Zones 1, 2, and 21.  DX’s have additionally been tested and approved by ETL for operation under load in a gaseous environment (14.5% acetylene). This is a key performance test required for Class 1, Division 1 products.

The DX’s rugged construction, compact size, cost-effective design,
IP 65 rating and unique safety and operating features make them a good choice for refineries, petroleum platforms, chemical and pharmaceutical plants, grain silos and other similar potentially hazardous applications.

CSA
   • IEC/EN 60309-1

   • IEC/EN 60947-3, AC22

   • EN 50014 /18/19 Zones 1 &2

   • EEx ed IIC T6; CENELEC certified

   • IEC 61241-3 for Zones 21 &22
