YB3-W, TH, THW, TA, TAW Series Explosion-proof Three-phase Asynchronous Motors (H63-355)

1. General Description

       This series of motors are developed from YB3 series motors, they are totally enclosed, self-fan-cooled, squirrel-cage and used in outdoor areas (W type), humid tropics areas (TH type), outdoor humid tropics areas (THW type), dry tropics areas (TA type) and outdoor dry tropics areas (TAW type). This series of motors are suitable to be used in hazardous area (class IIA, IIB and IIC; temperature class T1-T4) with explosive gas atmosphere. 

       The properties of this series motors meet the Industrial Standard JB/T7565.2 while the properties of flame-proof conform to GB3836.2, they can be made into ExdIIAT4 Gb，ExdIIBT4 Gb, and ExdIICT4 Gb.

       The rated power, electrical performance, synchronous speed and mounting dimensions of this series motors are the same as YB3 series motors.

       The main enclosure of this series motors is of protection degree IP55, cooling system is IC411,
