ATEX is the conventional name of the Directive 2014/34 EU for the equipment intended for use in potentially explosive atmospheres.

Motive DELPHI Ex motors differ from standard DELPHI motors because they are designed to be used, like motive "Ex" gearboxes, in the ATEX zones 1, 2, 21 and 22.

Cat	Dust	Gas	Zone	Atmospheres	DELPHI Ex
1		Yes	0	A place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor or mist is present continuously or for long periods or frequently.
2		Yes	1	A place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally.	Yes
3		Yes	2	A 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	Yes
1	Yes		20	A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently
2	Yes		21	A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.	Yes
3	Yes		22	A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only.	Yes

Motive DELPHI EX motors are in fact certified for such zones according to the norms EN 60079-0 - EN 60079-7 - EN 60079-31 by a notified body
