Plugs & Sockets | ATEX Certified | Zone 1 & Zone 2 Hazardous Areas
PRE Series 16 & 32 Amp Plugs and Sockets manufactured by Appleton ATX use a pin and sleeve design to deliver safe power to stationary and portable equipment in hazardous areas and those classed as Zone 1 and 2 and Zone 21 and 22. Suitable for use in damp, wet or corrosive environments, PRE plugs and sockets are keyed and color coded per IEC directives. The sockets are available in wall-mount, flush-mount and mobile versions.
♦ See our complete range of ATEX Plugs for hazardous area electrical power distribution at low voltage – this includes flameproof plugs according to the Ex d Explosion Protection concept.
Typical Hazardous Area Applications
- Lighting Systems
- Conveyors
- Heaters
- Motor Generators
- Air Conditioning Equipment
- Compressors
The Appleton ATXÂ PRE Series plug and socket system, certified and approved according to ATEX, is designed with a safe disconnect mechanism to insure maximum hazardous location and workplace protection.
PRE plugs feature contact separation in a flameproof chamber with the automatic electrical disconnection of each phase contained in a second flameproof chamber.
The same plug used in hazardous locations, including Zone 1 and Zone 2, can also be safely used with interlocking non-hazardous IEC 309 sockets. Different voltages are color coded for easy identification.
