ATX™ PRE Series 16 Amp Plugs and Sockets

Increased Safety

ATEX/IECEx:

Zone 1 and 2 - 21 and 22

II 2 GD

IP66 - IK09/10

Applications

• Plugs and receptacles are used with portable or stationery

electrical equipment such as:

— Lighting systems
— Conveyors
— Heaters
— Motor generators

  — Air conditioning equipment

— Compressors
— Pumps

•  For use in corrosive atmospheres and installations in Zone 1 
and 2 and 21 and 22 of the oil and gas industry; such as:

   — Reneries

— Chemical and petrochemical plants
— Pipelines
— Loading docks
— Onshore and offshore drilling platforms

Features

• Plug and socket system is designed with a safe disconnect

mechanism to insure maximum hazardous location protection:

  — The contact separation is in a ameproof chamber

— The automatic electrical disconnection of each phase is

contained in a second ameproof chamber

•  Short circuit protection is 20 kA, while normal reference is 
10 kA.

•  Different voltages are color coded for easy identication.

•  The receptacles are keyed to accept only ATX plugs (other plugs 
can not be inserted).

•  ATX plugs can be used in non-hazardous IEC 309 sockets.

•  Operating temperature of -40 °C to +55 °C (-40 °F to +131 °F)

Standard Materials

•  Wall Socket for 2P - 2P+E - 3P: high impact resistance 

polycarbonate

•  Wall Socket for 3P+E - 3P+N+E: high impact resistance 
berglass reinforced polyester

•  Plug, mobile socket and ush socket: polyamide
