Overview of DC circuit breaker functions

ADDM6DC series plastic shell circuit breaker is suitable for centralized photovoltaic power station system, 2p dc input voltage 500~1000V, 4P DC voltage can be up to 1500V.

Product Highlights:

1. It has the function of overload and short circuit protection

2. It can protect the line and power supply equipment from damage

3. It has the characteristics of small size, high segmentation capacity, short arc and anti-vibration

4. ADDM6DC MCCB: Centralized inverter application field:

The output of the photovoltaic string group is transferred to the DC combiner box, and the output is converted by the inverter DC/AC, and the output is AC and then boosted and connected to the grid. DC circuit breakers need to be installed on the DC side of the DC combiner box and inverter, and the working voltage is DC1000V→DC1500V.

5. ADDM6DC the structural characteristics of high protection accuracy and long life of small amps.

The mechanism components and trippers are designed and optimized by borrowing the M3 structural platform to ensure reliability and trip accuracy. Mechanical life: 10000 times, electrical life 2000 times

Use environment

1. The altitude of the installation site shall not exceed 2000m;

2. The ambient air temperature is not higher than +40°C and not lower than -5°C; and the 24-hour average does not exceed +35°C (except for special orders)

3. The relative humidity of the air at the installation site. **No more than 50 [%] at temperature +40°C, higher relative humidity can be allowed at lower temperatures, e.g. 90 [%] at 20°C. Special measures should be taken for condensation occasionally caused by changes in dry temperature.

4. There is no explosion risk medium in the air and there is no gas and conductive dust that can corrode the metal and destroy the insulation.

5. No rain or snow.

6. The pollution level is level 3.

7. Installation category: The installation category of the main circuit of the circuit breaker is I, and the installation category of the auxiliary circuit and control circuit that is not connected to the main circuit is II
