Do you know ?
Ex d Flameproof Protection
All electrical connections and equipment are enclosed in a housing strong enough to contain any explosion or fire that may take place inside the housing.
Ex e Increased Safety
All electrical connections and equipment incorporate special measures to reduce the probability of excessive temperatures and the occurrence of arcs and sparks in normal service.
Ex ia Intrinsically Safety
The electrical energy available in circuits and equipment, is limited to a level too low to ignite the most easily ignitable mixtures in a hazardous area. Intrinsically safe barriers, Zener or Transformer Isolated, are installed in the circuit to limit current and voltage in the hazardous area to prevent sparking under fault conditions.
