Ex e increased safety ATEX enclosures

Polyester ATEX junction box with cable glands

Our Ex e increased safety ATEX enclosures use additional construction measures to prevent excessive temperatures, arcs and sparks. In graphite-loaded polyester (BAS-P), aluminium alloy (BAS-A) or 316L stainless steel (BAS-I), more than 75 sizes are certified LCIE 11 ATEX 3062X for zones 1, 2, 21 and 22. Not sure which type of protection you need? Read our guide Ex d or Ex e: how to choose.

Definition: type of protection in which additional measures provide increased safety against excessive temperatures and arcs or sparks, inside and on the external parts of electrical equipment that does not produce them in normal service. The enclosure must provide at least IP54 for an enclosure containing bare live parts (IP44 if parts are insulated), and 7 J impact resistance for high mechanical risk (4 J for low risk).

Applications: junction boxes, control stations fitted with ATEX components, motors, luminaires.

BAS-P, BAS-A and BAS-I enclosures are certified LCIE 11 ATEX 3062X for zones 1, 2, 21 and 22. The BASR range (BASR-P, BASR-A, BASR-I) is certified TUV 20 ATEX 8601 / IECEx TUR 20.0101 (Ex eb ia/ib).

BAS-P: graphite-loaded polyester

Datasheets (PDF): BAS-P · BAS-P Cofatex · BAS-P lighting · BAS-P9 lighting switch · BAS-P2 grille

Glass-fibre reinforced, graphite-loaded polyester is antistatic, light and corrosion-resistant, suited to chemical sites and outdoor installations.

  • Control station, Instrum-Élec (junction box with terminals), BAS-P9 lighting box and lighting switch versions.
  • Direct connection or pre-wired.

BAS-A: AlSi 12 aluminium alloy

Robust aluminium alloy enclosure with RAL 7001 powder coating, for industrial applications that need good mechanical strength.

BAS-I: 316L stainless steel

316L stainless steel resists corrosive and salty atmospheres and frequent cleaning. Ideal for offshore, marine, pharmaceutical and food processing sites. Our 316L stainless steel enclosures
