Zone 1 & Zone 2 Stainless Steel Enclosures & Junction Boxes – ATEX Hazardous Area
Abtech SX enclosures are available in 14 sizes manufactured from stainless steel – 11 enclosure sizes are available in depths of 140mm or 200mm and 8 sizes are available in depths of 140mm, 200mm or 300mm.
The Abtech SX stainless steel range of hazardous area enclosures feature a high level of ingress protection (IP66/67) specifically designed to meet the demands of onshore and offshore environments with Zone 1 and Zone 2 locations. IP68 enclosures are also available for depths up to 120 ft to special order.
Stainless steel enclosures can be fitted with removable cable glands plates and a mild steel option (Abtech MSX) is available with a range of RAL colour selections.

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.
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.
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.

Fire Resistant Enclosures
Abtech SX enclosures and junction boxes are suitable for fire resistance and fire protection applications and when fitted with ceramic terminals meet the requirements of IEC 331 (750°C for 3 hours) and also BS6387/1983 (950°C for 3 hours).
- BS6387: test method for resistance to fire of cables, enclosures and junction boxes required to maintain circuit integrity under fire conditions.
Stainless Steel Enclosures
Abtech SX enclosures are manufactured from type 316 stainless steel – excellent corrosion resistance including pitting and crevice corrosion in the oil, gas and petrochem industries and offshore high-saline installations.
Abtech SX enclosures are effectively earthed using an internal/external earth stud fitted as standard which can be connected to the terminal mounting rail or component mounting rail. Earth studs can be fitted to the door and gland plates and rail mounted earth terminals or proprietary earth bars can be installed within the electrical enclosures.
