Flame Proof

Flame Proof


Product Description

The use of electrical motors in potentially explosive atmospheres is quite frequent these days. These motors have to be constructed in such a way that there is no risk of an explosion. An Explosion occurs when the following situations occur:

Presence of potentially explosive atmosphere
Existence of a source of ignition
Possibility of transmission of the explosion

ABB motors of flame proof design (type JHX) are TEFC, 3 phase squirrel cage induction motor (as per IS:2148 – 2004) for operation in hazardous location classified as Zone 1 and Zone 2 areas as per IS:5572.

Type : JHX Series

Output : 0.25 to 15 KW

Frame : JHX 71 TO JHX 160

Poles : 2….8

Motors suitable for high ambient temperature 50ºC.

Keeps an explosion which takes place inside the enclosure from propagating through gaps to the ambient.

Withstands the explosion pressure created inside the enclosures.

Benefits when dealing with special operating modes such as heavy stars and special applications.

All surface temperatures are selected to comply with the temperature class.

Suitability for use in temperature classes T1 toT4.

Can be used both in Zone 1 and Zone 2
