Working Principle The THED breaker uses a combined thermal-magnetic trip mechanism. The thermal element is a bimetallic strip that responds to sustained overload currents by heating and bending until it releases the trip mechanism. The magnetic element is a solenoid coil that responds instantaneously to high-magnitude short-circuit currents, providing rapid fault clearing. When tripped, the stored energy mechanism drives the contacts apart at high speed. The resulting arc is forced into the arc chute where it is split, cooled, and extinguished by the deionizing plates. The breaker handle moves to the tripped position, providing clear visual indication of the fault condition.
