Flameproof Junction Box Ex d – Zone 1 & Zone 2 Hazardous Area Junction Boxes

Product Overview

Flameproof Junction Box Ex d

Abtech SSD flameproof junction boxes (Ex d) are ATEX certified and suitable for Zone 1 and Zone 2 hazardous areas. The Ex d flameproof junction box is designed to house electrical and electronic apparatus within Zone 1 and Zone 21 hazardous areas.

Abtech SSD stainless steel junction boxes have an Ex d flameproof design allowing potentially sparking equipment to be safely installed in areas where explosive gases or dust may be present. The use of 316L marine grade stainless steel ensures maximum environmental protection for harsh onshore and offshore operating conditions.

Zone 1 Hazardous Area

A hazardous area location according to ATEX in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.

Zone 2 Hazardous Area

A hazardous area location according to ATEX in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, persists for a short period only.

ATEX Explained

The ATEX Directive consists of two EU directives describing the type of equipment and hazardous area location within a potentially explosive atmosphere. ATEX originates its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles.

Cable entries can be drilled in the enclosure or junction box door, sides or via the cable gland plates – cable entries can also be drilled through the rear face of the stainless steel enclosure (EEx’e’ hazardous area versions).

The hazardous area enclosures include a hinged, lift-off door secured to the junction box using 4 captive stainless steel screws which also maintain the correct compression on the gasket.
