The ATEX Certification (Intrinsically Safe Certification) is a system designed for electrical equipment used in hazardous environments, which prevents the generation of sparks or high temperatures capable of igniting explosive mixtures by limiting energy (electrical and thermal). The core principle is to design electrical equipment with limited energy to ensure that sparks or thermal effects produced during normal operation or in the event of a fault cannot ignite surrounding explosive mixtures (gases, vapors, dust, etc.).
This company's explosion-proof ratings are categorized as:
(1) ia Category: Electrical equipment that cannot ignite explosive gas mixtures under normal operation, with two counting faults applied, and non-counting faults under the most adverse conditions, is suitable for Zones 0, 1, 2, and 20, 21, 22.
(2) IB Grade: One counting fault applied under normal working conditions, pluszuiElectrical equipment that cannot ignite explosive gas mixtures under adverse conditions or non-counting faults is applicable for Zones 1, 2, and 21, 22.
(3) IC rating: Electrical equipment that cannot ignite explosive gas mixtures under normal operating conditions, suitable for Zones 2 and 22.
