| II 3G Ex dc ec IIB Gc | Zone 2 (Gas) |
New Micro Switches MFI-Ex certified ATEX and IECEx, suitable for use in Zone 2 (Gas).
NC positive opening, with snap-action operation with high reliability, equipped with self-cleaning switching contacts in silver alloy and available with the pin plunger or various types of actuation lever.
Reference standards: EN 80079-34, EN 60947-3, EN 61241-0, EN60079-0, EN60079-31, EN60079-1, UL 121201.
Directive: ATEX 2014/34/EU.
CLASSIFICATION AREA “Gas”:
Zone 2: place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
TYPE OF PROTECTION GAS
Restricted breathing case (Ex “dc ec”).
II 3G Ex dc ec IIB Gc in according with IEC 60079-0; 60079-15.
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 Micro Switches 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.
