Ⅰ,Overview of high-voltage AC circuit breaker

ARM6HU series moulded case circuit breakers are applicable to string photovoltaic power station systems. Their rated working voltage can be up to 1000V, and can be used in 500V and 800V systems.



Ⅱ,ARM6HU product highlights

1. Advanced and safe arc extinguishing system structure design;


2. Zero flashover can be achieved by installing the protective cover. Double insulation:

pole to pole connection and complete isolation of main circuit;The products are widely used in the field of new energy. AC MCCB: series inverter application (power station type): PV string is inverted by inverter DC/AC, and the output AC is boosted and connected to the grid after being converged by AC combiner box. AC combiner box and low-voltage side of box substation shall be equipped with AC circuit breaker, with working voltage of AC500V → AC800V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.

In order to improve the insulation performance and short-circuit breaking safety of the product, the reinforced insulating base plate and zero flashover cover are specially made

 

3、 Green:

We strictly control the raw materials, process processing technology and auxiliary materials of products according to the requirements of EU ROHS 2.0 directive.


4、Safe and reliable: extremely high mechanical life and electrical 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

 

5、ARM6HU small ampere is characterized by 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
