"<div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">There are two arrangement of operation of <a href=\"/products2098056/Circuit-Breaker.htm\"><strong>miniature circuit breaker</strong></a>. One due to thermal effect of over current and other due to electromagnetic effect&nbsp;</span></div><div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">of over current. The thermal operation of miniature circuit breaker is achieved with a bimetallic strip whenever continuous over current flows through&nbsp;</span></div><div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">MCB, the bimetallic strip is heated and deflects by bending. This deflection of bimetallic strip releases mechanical latch. As this mechanical latch is&nbsp;</span></div><div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">attached with operating mechanism, it causes to open the miniature circuit breaker contacts. But during short circuit condition, sudden rising of electric&nbsp;</span></div><div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">current, causes electromechanical displacement of plunger associated with tripping coil or solenoid of MCB. The plunger strikes the trip lever causing&nbsp;</span></div><div><span style=\"font-family:Microsoft YaHei;font-size:16px;color:#666666;\">immediate release of latch mechanism consequently open the circuit breaker contacts. This was a simple explanation of miniature circuit breaker</span></div><div><br /></div>"
