YB3 three-stage energy-efficient explosion-proof motor


Applicable to: Underground coal mines (non-excavating working faces) (Ex dⅠ) and factories (Ex dⅡAT4, dⅡBT4) containing methane and other gases or coal dust, containing flammable gases or steam and air of Groups A, B and T1 to T4 groups A place where explosive mixtures are formed.

Frame size: 100 ~ 315 Power: 1.5 ~ 200kW

Protection level: IP55 Energy efficiency level: IE2 (level 3)

Applicable to: Underground coal mines (non-excavating working faces) (Ex dⅠ) and factories (Ex dⅡAT4, dⅡBT4) containing methane and other gases or coal dust, containing flammable gases or steam and air of Groups A, B and T1 to T4 groups Place of formation of explosive mixtures

Features: Explosion-proof signs are ExdⅠ, ExdⅡAT4, ExdⅡBT4, the highest surface temperature of class Ⅰ does not exceed 150 ℃ (when coal dust may accumulate on the motor surface), and does not exceed 450 ℃ (when the motor surface does not accumulate or measures can be taken to prevent coal accumulation Dust)); the highest surface temperature of class Ⅱ should not exceed: T1 (450 ° C), T2 (300 ° C), T3 (200 ° C), T4 (135 ° C); the junction box can be made into three or six outlets respectively Terminals are suitable for both rubber-sheathed cables (or plastic cables) and steel pipe wiring.

Ambient temperature: Ambient temperature is -15 ℃ ~ 35 ℃ (under the coal mine) or -15 ℃ ~ 40 ℃ (factory)

Rated voltage: 380V, 660V, 380 / 660V.
