0.25kW 415v ATEX Motor - 4 Pole
Zone 1 & 21 IP65 – Fully certified
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). These three
phase motors are regularly used with an AC Inverter to optimise efficiency and compatibility.
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.

Features
Compliant
The ATEX 0.25kW motors comply with the Standards IEC/EN 60079-0,60079- 1,60079-31 for atmospheres where gas or combustible dust is present.
ATEX Rating
Areas classified into zones must be protected from sources of ignition. The equipment used must conform to the ATEX regulations to keep safety
standards. ATEX rated equipment are marked with a small ‘EX’ sign.
Prioritising Safety
Winding cables connected to the terminal box by means of terminal blocks or by flameproof bushings. Mechanical components painted with
protective paints; - stainless steel nameplate, - anti-corrosion screws. Cast iron frame, terminal box and endshields are highly resistant to
impact. Low friction dust seals.
