FAQ

Q: What is the meaning of YBX3? What is the explosion-proof level?

A: YBX3 is a high efficiency explosion-proof three phase induction motor. Standard explosion-proof mark: Ex d I Mb / Ex d II BT4 For use in coal mine and general flammable gas situations.

Q: What industries and circumstances are YBX3 explosion-proof motors suitable for?

A: Widely used in petroleum, chemical, coal mine, pharmaceutical, grain processing, paint spraying, and other places with flammable and explosive gas or dust mixtures.

Q: What is the efficiency level of YBX3 series explosion-proof motor?

A: The YBX3 series adopts the ultra-high energy efficiency standard of IE3. Compared with the conventional YB2/YB3 motors, it has low energy consumption, low temperature increase and extended service life.

Q: Can YBX3 explosion-proof motors work outdoors in rainy and humid environments?

A: The standard protection grade is IP55. It resists splashing water and dust intrusion, and can be used outdoors with rainproof covers. For severe damp corrosive sites, customized anti-corrosion coating is available.

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 blocks internal sparks from igniting external explosive media, while ordinary Y motors have no flameproof structure and cannot be used in hazardous explosive areas.
