Hazardous Area (ATEX), Explosion Proof Junction Boxes

Explosion Proof Junction Boxes for Power Distribution in Hazardous Areas Zone 1, Zone 2, Zone 21 & Zone 22 with ATEX Certification

Spelsberg Abox ATEX junction boxes (Ex rated) are certified for use in explosion risk, hazardous areas Zones 2 and 22 according to ATEX 100a. ATEX  explosion protected junction boxes are halogen free and operate 400V-690V. Abox Ex junction boxes provide explosion proof enclosure performance for hazardous area zones 2 and 22, available with or without terminals.

Explosion Proof Electrical Enclosures & Junction Boxes -electrical equipment may include arcing and sparking (incendive) devices and flammable mixtures which may enter the enclosure or junction box. The explosion proof electrical enclosure construction is designed to contain an internal explosion and prevent transmission of sufficient energy to ignite a potentially flammable atmosphere outside the enclosure or junction box.

T&D UK distribute an extensive range of junction boxes and electrical enclosures including polycarbonate, stainless steel and aluminium types for industrial, hazardous areas (flame and explosion proof, ATEX Zone 1 and 2), LSF halogen free, fire resistant and high voltage termination enclosures. 


Spelsberg Abox Explosion Proof Polycarbonate Junction Boxes - Features :
Suit 1.5-35sqmm cables       IP65 or IP66 ingress protection     Halogen free
UV and weather resistant     -35 to +40 degrees celsius
 

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, cable transits, cable cleats, mobile phones, laptops, digital cameras, conduit systems, portable lighting (torches, handlamps, headlamps).

Explosion Proof Equipment in Hazardous Areas : 3 elements are required in order to create a hazardous area : i) air ii) flammable gases, vapours, mists, dusts iii) source of ignition. An explosive atmosphere is created when air and a flammable medium mix such that a rise in temperature or an electrical spark produces an explosion. An explosive atmosphere can self ignite if the local temperature rises above the self-ignition temperature in the hazardous area, this varies for different flammable mediums (gasses and dusts). Explosive atmospheres are caused by a mixture of gases, vapours, mists, dusts and air - it the explosive atmosphere is caused by gases, vapours and mists the hazardous area is coded G. If the explosive atmosphere is caused by dusts the hazardous area is coded D.

Explosion Groups - explosion protected hazardous area electrical equipment, including plugs and sockets, is classified in terms of the ignition temperature, the ignition capability and flame transmission capacity of the explosive atmosphere in which it operates. The hazardous area classification for electrical equipment is divided into 2 groups depending on whether located above or below ground : Group I or 1 - for use below ground in areas susceptible to firedamp, Group II or 2 for all other areas. Group II hazardous area electrical equipment is further divided into three sub groups depending on the ignition and flame transmission characteristics of the explosive hazard - these sub-groups are designated as IIA, IIB and IIC zones.
