The mini circuit breaker use high accuracy bimetal for inverse time lag thermal protection element, accurate protection characteristic. The operating mechanism is four link mechanism, small operating physical force , reliable tripping, high sensitivity;

Instantaneous trip, electromagnet, light moving iron core, small interval, quick response, high sensitivity, inner store structure, absolutely no lock phenomena, enhance the reliability much; Changed the moving contact from crossbeam type to erect type, added rigidity, which ensures the contact s switch in on at a thermal state. Small bulk of moving contact, small operating interval, which ensures the speed of moving contact after break off,in favor of arc distract quickly;

The mini circuit breaker uses big arc chute, arcs track connected by iron acr runner, decreased the arc resistance, it can avoid intercept, 13 pieces grill, the arc can be cut, cooling, extinguish, sprying arc lip use multilayer grill can cooling, extinguish arc more, mostly ensured zero arcing. It can avoid the arc short circuit between poles;

Arc chute protected by special organic material, it will bring a lot of insulating material smoke at high temperature, enhance of the pressure. Controlling the cascade direction of metal smoke in effect, the insulat- ing material smoke can cooling the arc fan and enhance the arc resis- tance and voltage, it ensured arc extinguish quickly. The insulation ma- terial also avoid the case s burning loss, ensured the product s high insu- lation performance.

The mini circuit breaker is well current limiting, very short of arcing time, long life, reliable performance; has obvious position state indicate; reasonable of structure design, so power supply input wire can random choose; connecting terminal adopt frame construction, no matter soft, rigidity leads are can hard connect; complete accessories, the mini circuit breaker can with auxiliary contact, alarm contact, shunt release, undervoltage release and residual current operating protector module etc. They are facility for intelligentize apply.
