OPTIONAL FEATURES AND ACCESSORIES

ATEX Directive 94/9/EC APPROVAL
FOR HAZARDOUS LOCATIONS

ATEX is a European designation that
deals with standards for equipment and
protective systems intended for use in
potentially explosive atmospheres. This
approval is required for switches intended
for use in hazardous locations, especially
important to OEMs who export to Europe
and contractors specifying or purchasing
products for European applications.
XCN option adds special features to
Ashcroft 700-Series switch enclosures
that meet the requirements for the highest
levels of security and danger,
such as:
• Special locking device requiring an Allen

wrench to remove cover

• Special vents that blow out should the

diaphragm rupture, thus preventing
pressure build-up in the enclosure

• Special conduit plug requiring an Allen

wrench for removal

• Available on pressure, temperature and

differential pressure models

• Meets Explosion Class EEx d IIC T6
