The CYM7E three-phase unbalanced commutation switch is installed at the end of the distribution network; Afterwards, install several single-phase loads for households; By carrying and transferring single-phase loads; Thereby addressing the phenomenon of unbalanced three-phase loads; And a switch device that can disconnect fault currents.

Product Features

1. Essentially, it is a “switchgear” that complies with the GBT14048.3 standard, carries overload current through 3C certification, and conforms to GB14048

◆ Breaking short-circuit current, 35KA breaking capacity, in compliance with GB140482 requirements

◆ It has visible breakpoints and can prevent short circuits caused by lightning strikes.

2. Switching supply phase with load

The A, B, and C phases have mechanical locking function to prevent phase to phase short circuit or breakdown.

◆ Stable switching during commutation, completed within 10 milliseconds, with a dispersion of less than 1 millisecond.

Long lifespan, with a mechanical lifespan of 100000 cycles, meeting the requirements for dynamic adjustment of single-phase loads.

Switching with load more than 10000 times, meeting the requirements of GB14048.2 for electrical life.

3. Energy saving and loss reduction to reduce copper, iron, and line losses

Electromagnetic compatibility complies with GBT14048.3 standard, with no rejection or abnormality.

The self power consumption is less than 5 watts, and the communication adopts low-power wireless widely used for meter reading.

work environment

1. The ambient temperature is between -25 ℃ and+75 ℃, and the altitude does not exceed 2000 meters.

2. Relative air humidity: When the monthly average humidity of the wettest month does not exceed 25 ℃, the maximum monthly average relative humidity of that month shall not exceed 90%, taking into account the condensation that occurs on the surface of the product due to temperature changes

3. The external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction, and large electromagnetic interference (such as high-power electric motors or frequency converters) should be avoided as much as possible near the product. There should be no explosive or corrosive gases, no rain or snow invasion, and it should be dry and ventilated.

4. Pollution level: Level 3; Installation category: III.
