Intelligent Conventional Circuit Breaker

Features: 
1) Applicable for distribution network with rated frequency of AC 50Hz, rated 
    voltage of 400V and 690V, and rated current of 630 to 3,200A to distribute 
    electric energy protection circuit and prevent power equipment from the 
    harm of overload, under-voltage, short circuit and single-phase earth
2) Provided with intelligent protecting function and precise selective protection,

    breaker can enhance the dependability of power supply and avoid unwanted
    power cut
3) Has functions of shunt excitation release, under-voltage release, electric 
    operating mechanism, closed electromagnetic rated operating voltage 
    as well as required power
4) The operating voltage of intelligent release is AC 380V / 220V and DC 200V / 110V
5) In accordance with the standards of IEC947-2 and GB14048.2

This intelligent breaker is specified into fixed type and drawer type according to
installation ways. In terms of operating ways, it can be classified into motor
operation and mechanical operation (for the use of examining, repairing and maintenance).

In the light of poles, it can be classified into 3 poles and 4 poles.

According to categories of trippers, it can be sorted with: 
1) Intelligent type over-current controller (H for communication type, M for 
    general intelligent type, L for economic type)
2) Under-voltage instant or delayed acting tripper
3) Releasing tripper
