Compliant with:

IEC 60079-0 & EN IEC 60079-0 – Equipment – General requirement
IEC 60079-1 & EN IEC 60079-1 – Equipment protection by flameproof enclosures “d” IEC 60079-7 & EN IEC 60079-7 – Equipment protection by increased safety “e” IEC 60079-11 & EN IEC 60079-11 – Equipment protection by intrinsic safety “i” IEC 60079-18 & EN 60079-18 – Equipment protection by encapsulation “m”
IEC 60079-31 & EN 60079-31 – Equipment dust ignition protection by enclosure “t”


  • Type of protection Ex eb: It provides an impact resistant enclosure for electrical equipment and ensures that the contents will not produce a spark, temperature or current creepage that could ignite the external flammable atmosphere in a hazardous area zone, location or workspace.
  • Type of protection Ex tb: It avoids combustible dust (IIIC) penetration into the enclosure and ensures surface temperature limitation for use in explosive dust atmospheres.


  • Type of protection Ex db: Electric equipment is installed in enclosure suitable to withstand the pressure raised during the internal explosion and avoids flame transmission to the external potentially explosive atmosphere.
  • Type of protection Ex ia / ib: The energy of the circuit which could be capable of igniting a potentially explosive atmosphere is limited so that neither sparking nor heating of the electrical components can ignite the surrounding potentially explosive atmosphere.
  • Type of protection Ex mb: Encapsulation allows the separation of the alive parts from the explosive atmosphere.
