NepalExplosion-proof motor

Product Description

Product application areas:Places containing methane and other gases or explosive mixtures of combustible gases or steam and air formed by underground coal mines (non-mining working faces)(Ex d I) and factories (Ex d II AT4, d II BT4).

Product features:The maximum surface temperature of Ex d I, Ex d II AT4, Exd II Bt4 and Class I shall not exceed 150 ℃ (when coal dust may accumulate on the surface of the motor) and 450 ℃ (when the surface of the motor will not accumulate or measures can be taken to prevent the accumulation of coal dust); The maximum surface temperature of Class II shall not exceed; t1 (450 ℃), T2(300 ℃), T3(200 ℃), T4(135 ℃); The junction box can be made into three or six outlet terminals respectively, which is suitable for rubber cable (or plastic cable) and steel pipe wiring.

Ambient temperature:-15 ℃ ~ 35 ℃ (underground coal mine) or -15 ℃ ~ 40 ℃ (factory)

Rated voltage:380V、660V、380/660V
