Scope of appliance

JCGCK type low voltage draw-out switchgear is suitable for such electric power system as power plant ,electric substation and industrial and mining enterprises and high buildings, whose rated service voltage is 380V, and also with AC three-phase four-wire system or TN-S. It's function is power receiving, feed,  compensation of watless power, and calculating  the electric energy, lighting, and the centralized control of motors.

The product is in accord with such standard as GB7251, JB/T9661<LV draw-out switchgear>, IEC62439.1 .

Service condition

1. Altitude:≤2000m

2. Temperature of the enviroment竊�5��/span>~+40��/span>竊�aily average temperature: ≤35��/span>. 

3. Relative humidity: When the temperature is +40��/span>, it is not higher than 50%; the lower temperature, the bigger relative humidity is allowed. For example, when the enviroment temperature is +40��/span>, it is 90%.

4. The switchgear shall be installed where there is no violent shake, no impact , no fire, no explorsion and no corrosive danger to the electirc unit.

5. When installing,the angle of inclination is less than 5°,

6. The shipment and storage temperature is -25��/span>+55��/span>, within +70��/span>(less than 24h)
