Zone 1 & Zone 2 Isolators, Hazardous Area Isolators

Isolators - Zone 1, Zone 2 ATEX Certified Hazardous Area Isolators

Zone 1 and Zone 2 isolators (switch disconnectors) are ATEX certified for hazardous area installation - Craig & Derricott range of ATEX certified Zone 1 and 2 isolators are housed in heavy duty cast enclosures for use in hazardous areas. Zone 1 and Zone 2 isolators are available with 16a, 25a, 40a, 63a, 80a, 100a, 125a, 160a, 200a, 250a current ratings for hazardous are electrical installations.

Zone 1, Zone 2 Isolators, Hazardous Area ATEX Certification Code
Ex d II 2 GD IIB T4, T5 or T6 (IP65)

High quality heavy duty cast electrical enclosures are used throughout the hazardous area isolator range - Zone 1 and Zone 2 cast iron isolators 16A-80A, cast aluminium isolators 63A-250A. The electrical enclosures housing the hazardous area ATEX certified isolators (Zone 1 and Zone 2) are supplied with large cable entries which can be fitted with approved hazardous area reducers to suit cable requirements. All load switching interiors of the Zone 1 and Zone 2 isolators are supplied as either TP&N (switched neutral) or 6P and have AC23A ratings to BS EN 60947-3.

Hazardous Area Zones Classification
Zone 1 - where flammable atmosphere is likely to occur during normal operation.
Zone 2 - where flammable atmosphere is not likely to occur during normal operation and if it does will only exist for short period of time, typically less than 10 hours per year.

ATEX Certified Electrical Equipment for Hazardous Areas
ATEX is the name given to a set of European Directives relating to Hazardous Area Electrical Equipment Installations (Flammable Atmospheres) to avoid industrial accident or incident. ATEX Directive 94/9/EC (ATEX 95), is a directive adopted by the EU under the “New Approach” strategy.

The “New Approach” ATEX directive supersedes the “Old Approach” ATEX Directive, the Potentially Explosive Atmospheres Directive, 76/117/EEC – ATEX 94/9/EC (ATEX 95) facilitates free trade in the EC for hazardous area electrical equipment intended to be used in potentially explosive atmospheres. ATEX Directive 94/9/EC (ATEX 95) covers “Electrical Equipment”  used in hazardous areas with potentially explosive atmospheres created by presence of gases, vapours, mists or dusts.  T&D UK stock and distribute an extensive range of ATEX Certified Electrical Equipment for Hazardous Areas including cable glands, electrical enclosures, junction boxes, plugs and sockets, cable joints, control stations, isolators, cable transits, cable cleats, mobile phones, laptops, digital cameras, conduit systems, portable lighting (torches, handlamps, headlamps).
