Flame Proof

  • Overview
  • 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

  • Technical Specification
  • Type : JHX Series

    Output : 0.25 to 15 KW

    Frame : JHX 71 TO JHX 160

    Poles : 2….8

  • Features
  • 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

  • Application
  • Highest efficiency class
    Suitable for 50 C ambient temperature for rugged environment
    Cast iron construction for high structural strength
    Inner bearing cover on driving side restricts axial play
    Reliable, efficient & cost effective for various industrial Applications
    Low noise
    Reduced downtime
    Reduced energy bill
    High resistance to abnormal operating conditions
    High tolerance to thermal stresses from frequent starts
    Eco – friendly operation for limiting carbon emissions
    High efficiency levels save energy, enable cooler motor running for extended bearingand winding lifetime
