Sontouec The Latest Products for Three-Stage Protection Small MCB 2p 40A DC Miniature Circuit Breaker

SONTOUEC The lastest products for Three-stage protection small MCB 2P 40A DC miniature circuit breaker 

Three-stage protection small DC miniature circuit breaker applies a series of proprietary technologies of our factory, such as advanced electronic delay control technology, fault current sampling element and so on.
The short delay action performance is independent of the power supply voltage. At the rated current, the electronic control circuit basically has no voltage, realizing small volume and precise delay protection.
For the purpose of ensuring the demand of power protection system with high service life and reliability of products, the guarantee ability of DC power supply is comprehensively improved.

 three-stage protection small DC circuit breaker is the core project of independent development of new products in our factory and a major technical innovation in the field of DC distribution protection.
In addition to the outstanding advantages of accurate and reliable delay protection function, it also has the smallest year-on-year volume  (36mm width ). stay
While effectively reducing the space occupied by distribution appliances, it will also greatly improve the protection level of DC power supply system.

When the lower level is a three-stage DC miniature circuit breaker and the lower level is a two-stage or three-stage DC circuit breaker, the level difference is level 2. When the short-circuit current is 25 ~ 40 times the additional current of the lower level circuit breaker, the scale is accurate.

Specifications

It can meet the power storage capacity of power system below 1000ah
The differential coordination of pool group DC system or the fault current after current limiting of gm5b-40 lower circuit breaker shall not be greater than the differential coordination of 1000A DC system.
