YFB71-355 series dust explosion-proof three-phase asynchronous motorDetailed product description：

1、 Scope of application
The YFB71-355 series dust explosion-proof three-phase asynchronous motor is a dust explosion-proof three-phase asynchronous motor with the explosion-proof mark DIPA21TAT4. Its explosion-proof performance complies with the provisions of GB12476.1-2000 "Electrical equipment for use in environments with combustible dust - Part 1: Electrical equipment protected by enclosures and restricted surface temperature - Section 1: Technical requirements for electrical equipment". It is suitable for factories with combustible, non-conductive dust, hazardous areas of zones 21 and 22, and temperature groups of T1, T2, T3, and T4.
This series of products is not suitable for explosion hazardous areas caused by substances that can burn without oxygen in the air (such as gunpowder and explosives) or ignition materials, nor is it suitable for explosion hazardous areas where combustible dust and gas coexist.
Except for the appearance of the junction box, the rated power, flange type, electrical performance, and installation dimensions of this series of motors are the same as those of YB2 series motors.
