ATEX Motor Zone 1 and 21 - 2 pole - 45kW
ATEX EXD Zone 1 & EXTD Zone 21
Zone 1 – Areas where an explosive atmosphere is likely to develop during normal conditions. Flameproof electric motors or motors with added protection means can be installed in this zone (for the latter, restrictions by the standards apply).
Zone 21 – Areas where an explosive atmosphere is likely to develop during normal conditions. Electric motors certified in compliance with the ATEX directive with IP6X protection rating can be installed in this zone.
