Product Description
This switchgear is suitable for three-phase five wire power supply systems with AC frequency of 50 (60) Hz, rated working voltage of 400V, 660V, rated current of 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, and broadcasting and television communication centers to control power generation, transmission and distribution, energy conversion, and energy consumption equipment.
Working conditions
The ambient air temperature shall not exceed+40 ºC, not be lower than -5 ºC, and its average temperature shall not exceed+35 ºC within 24 hours;
The relative humidity of the surrounding air does not exceed 50% at the highest temperature of+40 ºC, and there is a higher relative humidity at lower temperatures, such as 90% at+20 ºC. However, considering that moderate condensation may occur occasionally due to temperature changes;
For indoor use, the altitude of the place of use shall not exceed 2000m;
It should be installed in a place without severe vibration and impact, as well as in a place where electrical components are not corroded.

Adopting intelligent controller control, with complete functions, reliable performance, and automatic compensation mode: the power factor can be increased to 0.9 or above;
Real time display of power factor of the power grid, display range: lagging (0.00-0.99), leading (0.00-0.99);
It has multiple comprehensive protection functions such as overvoltage, harmonic, overcompensation, system fault, phase loss, overload, etc;
Memorize the set parameters, and the system will not lose the parameters after a power outage. After the power grid returns to normal, it will automatically enter the operating state without the need for personnel to be on duty;
According to the load balance of the power grid, phase separation compensation or mixed compensation can be adopted;
Strong anti-interference ability, able to withstand direct input of 2000V disturbance pulses from the power grid, higher than national professional standards.
