This product is widely applied to the Power Center (PC) for power distribution and the Motor Control Center (MCC) in power plants, substations, industrial and mining enterprises, and high-rise buildings. It serves as a low-voltage complete power distribution device for power distribution, centralized control of motors, and reactive power compensation in power generation and power supply systems with an alternating current frequency of 50-60Hz, a rated working voltage of 1kV and below, and a rated current of 6300A and below.

The entire cabinet adopts a assembled combined structure, with installation through modular holes. The components have strong versatility, good applicability, and a high degree of standardization. The upper part of the cabinet body is the busbar chamber,the front part is the electrical appliance chamber, and the rear part is the cable inlet and outlet chamber. Each chamber is separated by a steel plate or an insulating plate to ensure safety.

The door of the drawer compartment of the MCC cabinet and the operating handle of the circuit breaker or disconnector are equipped with a mechanical interlock. The door can only be opened when the handle is in the off position. The incoming switch, the tie switch, and the drawers of the MCC cabinet have three positions: the on position, the test position, and the off position. According to the incoming power requirements, a busbar bridge can be installed on the top of the switchgear cabinet.

Type description

Normal service condition

The ambient air temperature shall not be higher than +40℃ and not lower than -5℃, and the average temperature within 24 hours shall not be higher than +35℃. When these limits are exceeded, the capacity shall be derated for operation according to the actual situation.

It is for indoor use, and the altitude of the installation locatin shall not exceed 2000m.

The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40℃. At lower temperatures, a higher relative humidity is allowed. For example, it is 90% at +20°℃. The influence of occasional condensation caused by temperature changes should be taken into account.

When the device is installed, the inclination from the vertical plane shall not exceed 5°, and the entire group of cabinet rows shall be relatively flat.The device shall be installed in a place without severe vibration and impact, and where the electrical components will not be subject to undue corrosion.
