Ⅰ.Overview of ARM6DC photovoltaic new energy DC circuit breaker

ARM6DC series moulded case circuit breakers are applicable to the centralized photovoltaic power station system. The DC input voltage for 2P is 500~1000V, and the DC voltage for 4P can be up to 1500V



Ⅱ.Highlights of ARM6DC photovoltaic new energy DC circuit breaker

1. With overload and short circuit protection functions

2. It can protect lines and power equipment from damage

3. It has the characteristics of small size, high breaking capacity, short flying tiger, good anti vibration, etc

4. ARM6DC MCCB: Application field of centralized inverter: PV string is output to DC combiner box for confluence, and then DC/AC inverter is used for inversion. After AC output, the voltage is boosted and connected to the grid. DC combiner box and DC side of inverter shall be equipped with DC circuit breaker, with working voltage of DC1000V → DC1500V.

5. ARM6DC small ampere has the structural characteristics of high protection accuracy and long service life.

The mechanism components and release are designed and optimized on the M3 structure platform, ensuring the reliability and tripping accuracy. Mechanical life: 10000 times, electrical life: 2000 times



Ⅲ. Usage scenario of ARM6DC photovoltaic new energy DC circuit breaker



Ⅳ.ARM6DC and ARM6HU patented technology & design innovation

1. Large opening distance

2. Large capacity metal anti-dissociation grid

3. Narrow slit pressurized air blowing solution

Ⅰ. The altitude of the installation site should not exceed 2000m.

Ⅱ. The surrounding air temperature is not higher than +40℃ not lower than -5℃; and the average value of 24 hours does not exceed +35℃ (except for special orders)

Ⅲ. The relative humidity of the air at the installation site. The highest temperature +40 ℃ not more than 50 [%], at lower temperatures can be allowed to have a higher relative humidity, for example, 2O ℃ when up to 90 [%]. Special measures should be taken for the condensation occasionally generated by dry temperature change.
