Ex i Intrinsic Safety | Explosive Atmospheres & Explosion Proof Protection Concepts

Ex i Intrinsic Safety

Ex i Intrinsic Safety is an explosion protection concept in which the electrical energy within the equipment is restricted to a level which is below that what may cause an ignition or to limit the heating of the surface of the hazardous area equipment.

There are two main sub types to Ex i Intrinsic Safety protection, these being “ia” and “ib”, used for the classification of equipment intended for use in hazardous area locations and explosive atmospheres.

Type “ia” Intrinsic Safety protection allows for the occurrence of two faults during operation; Type “ib” explosion protection allows for the occurrence of one fault during operation.
