FAQ

Q：What does YBX3 stand for and what explosion-proof grade does it belong to?

A:YBX3 Flameproof High Efficiency Three phase ASynchronous Motor. Its explosion-proof mark is Ex d I Mb / Ex d IIB T4 which is a typical explosion-proof mark for coal mine and general flammable gas environment.

Q: Which industries and circumstances are YBX3 explosion-proof motors relevant to?

A: Widely utilised in petroleum, chemical, coal mining, pharmaceutical, grain processing, paint spraying and other locations having flammable and explosive gas or dust combination.

Q：What is the efficiency grade of YBX3 series explosion-proof motors?

A:YBX3 series motors meet IE3 ultra-high energy efficiency standards, with low energy consumption, low temperature increase and extended service life than conventional YB2/YB3 motors.

Q: Can YBX3 explosion-proof motors be used outside in humid and wet environments?

A：The standard protection grade is IP55. It can stand water splash and dust incursion. And may be used outside with weather proof coverings. For severe wet corrosive situations, anti corrosion coating can be customised.

Q：What is the difference between YBX3 and ordinary Y series non-explosion-proof motors?

A：YBX3 adopts thickened flameproof shell, precise explosion-proof clearance and sealed wiring chamber. It can block internal sparks from igniting external explosive media, while ordinary Y motors have no flameproof structure and cannot be used in hazardous explosive areas.
