Small leakage circuit breaker basic introduction



The circuit breaker and beautiful shape, small volume, light weight, high breaking capacity, tripping rapidly, guide the installation, and parts using high flame retardant and impact resistant plastic shell, high performance and reliable. Circuit breaker by shell and handle, the operating mechanism, contact system, thermal trip, magnetic trip and arcing cover. Circuit breaker current is switched on, the bimetallic strip hot deformation, when the current overload reaches a certain extent, the excessive degree of bimetallic strip deformation promote trip action, when the trip through the short-circuit current, electromagnetic systems promote trip action immediately, so as to protect the electric equipment: tripping characteristics has been adjusted when delivery from factory. When used without adjustment and maintenance.
