The "n" protection concept - Category 3 products - applies to electric equipment and components:

  • belonging to group II - category 3
  • producing no sparks
  • producing limited energy

This concept applies only to sensors situated in locations or potentially explosive atmospheres, either gases, mists or vapours, where an explosive mixture is only very rarely to occur in case of abnormal operation and during very short periods.

The entire range of ATEX certified temperature sensors manufactured by CORREGE may receive the "n" protection concept label provided that marking requirements are complied with:

Each temperature sensor under "n" protection concept is delivered with an individual mounting instructions datasheet and an EC-type declaration of conformity.
