Environment Requirement:

1, the ambient air temperature is not higher than +40 ℃, not less than -5 ℃, 24h the average temperature shall not be higher than +35 ℃, over time, according to the actual situation to run;

2, indoor use: the location of the altitude of not more than 2000m;

3, the ambient air relative temperature of +40 ℃ when not more than 50%, at a lower temperature to allow a greater relative temperature, such as +20 ℃ when 90%, should be taken into account due to temperature changes may occur accidentally condensate The influence of the dew;

4, the installation of the device with the vertical slope of not more than 5 ℃, and the whole set of relatively flat column (in line with GBJ232-82 standard);

5, the device should be installed in the absence of severe vibration and shock and not enough to make electrical components should not be corrosive places;

6, the user has special requirements can be resolved in consultation with the manufacturer.


GCK low-voltage withdrawable switchgear is widely used in power plants, substations, factories and mines and high-rise building power distribution center PC and motor control center MCC, as AC 50-60Hz, rated working voltage of 660V and below, rated current 4000A and below the hair, the power supply system in the distribution, the motor centralized control, reactive power compensation using the low-voltage power distribution unit. Three-phase three-wire or three-phase four-wire system, as a low-voltage distribution system for substation, feed or motor dedicated. GCK low-voltage withdrawable switchgear to maintain the electrical performance is higher than similar products on the basis of increased capacity and mechanical strength, and has advanced structure, good looks, high degree of protection, safe and reliable, easy maintenance and other characteristics; Low voltage switchgear replacement products.
