YB3-80 ~355(IIC) flameproof three-phase asynchronous motor
This series of motors is derived from YB3 series with fully enclosed self - fan-cooled squirrel cage isolation
Explosion-type three-phase asynchronous motor is a higher explosion-proof motor in China. With every
Explosive structure advanced, high reliability advantages.
The explosion-proof performance of this series motor conforms to GB3836.2-2000 "Explosive Gas"
Electrical equipment for environmental use - Part 2: flameproof type "D" and IEC standard
The specification of IEC79-1, made of ExdIICT4 Gb, is suitable for factories with IIC grade temperature groups
Other dangerous places where explosive gas mixtures of group T1~T4 exist.
In addition to the differences in the appearance of the junction box, this series of motors have rated power and flange type
Formula, electrical performance and installation size are the same as YB3 series motor. Body of motor
The protection class of the shell is IP55, in accordance with the provisions of GB/T4942.1. Cooling mode:
IC411.
