Appleton ATX SWd Series

Hazardous Area Switch

Product Category: Switches | ATEX Certified | Zone 1 & Zone 2 Hazardous Areas

Flameproof ATX SWD Series 16 and 32 Amp switches, circuit breakers and “break glass” call points manufactured by Appleton ATX are designed to prevent operation in explosive atmospheres during connect and disconnect operation of lighting and light power loads. The switches ideal for use in hazardous areas where ignitable vapors, gases or highly combustible dusts are present.

♦ 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

Chemical Plants
Petrochemical Plants
Refineries
Other Process Industries

Appleton ATX SWE switches feature two threaded entries, one at the top and one at the bottom, M20 or M25 and a padlockable handle. The switch mechanism is fixed at the bottom of the box.
