Reference standards: EN 80079-34, EN 60947-3, EN 61241-0, EN60079-0, EN60079-31, EN60079-15.

Directive: ATEX 2014/34/EU

Zone 2: area in which an explosive atmosphere in the form of gas concentration in the air can occur for a short period due to a breakdown or malfunction.
TYPE OF PROTECTION GAS: Restricted breathing case (Ex “dc ec”)
MARKING: II 3GD Ex dc ec IIB T5 Gc according to IEC 60079-0; 60079-15.
PRINCIPLE: limited in power dissipation (ΔT limited), so the depression which is created when de-energized, is such as to delay the entry of explosive atmosphere for a time limit specified by the standard.
The Microswitch ATEX IECEx find application in many fields such as: control valves, actuators, conveyors, material handling and in general in petrochemical plants.
The type of materials and the internal design of the elements, conform this component for use in areas with potential explosive atmospheres due to the presence of gas in accordance with the ATEX Directive 2014/34/EU.
