YBFBX Composite Explosion proof Three phase Asynchronous MotorDetailed product description：

YBFBX composite explosion-proof three-phase asynchronous motor is suitable for hazardous areas where combustible gases and combustible dust mixtures may exist in industries such as petroleum, chemical, mining, metallurgy, power, machinery, pharmaceuticals, textiles, grain processing, and synthetic materials. It is applicable to Zone 1 and Zone 2 for combustible gases; The applicable areas for combustible dust are Zone 21 and Zone 22, making it an ideal power equipment with strong adaptability. Note: 1) This motor is not suitable for dust or self igniting substances that can burn without the need for oxygen in the atmosphere. 2) This motor is not suitable for electrical equipment used in coal mines underground and on coal mine surfaces where gas and/or combustible dust pose a danger.

Basic characteristics of YBFBX composite explosion-proof three-phase asynchronous motor

Main junction box
The main junction box with frame number 63-355 is located on the top of the motor (viewed from the motor shaft extension end), and the outlet can be adjusted in four directions. However, when the outlet of the junction box faces back (toward the non shaft extension end), due to the influence of the lifting ring, it is necessary to lift the motor in place at the installation site, remove the lifting ring, open the junction box cover, loosen the connecting bolts between the junction box and the motor base, and install the outlet of the junction box base note. Standard configuration for incoming wire of junction box: horn mouth incoming wire.
Optional configuration: threaded steel pipe wiring or explosion-proof gland head inlet.
