Miniature circuit breaker

The circuit breaker must detect a fault condition; in low voltage circuit breakers this is usually done within the breaker enclosure.
once a fault is detected, contacts within the circuit breaker must open to interrupt the circuit; some mechanically stored energy (using something such as springs or compressed air) contained within the breaker is used to separate the contacts, although some of the energy required may be obtained from the fault current itself. Small circuit breakers may be manually operated; larger units have solenoids to trip the mechanism, and electric motors to restore energy to the springs. At adhunik basics of the all the devices are very strong and unique. Body is made of “polybutaline terapythalate polyesterpolymer chip ”which has highly desirable thermal & electrical properties such as fire get extinguished when it moves from one molecule to another in such kind of material. “action is look like of fire proof materials” making breaking fixed and moving contact- moving- brass plate inlayed by pure silver making room for electrons to flow in a large area with minimum resilience. Fixed contact specially designed to make sure that there is no air gap between the two contacts even after large no of operations, make brake is perfect ,no secondary arc can develop - “action is a weld free mechanism” a common problem with many other designs arc chute tri coating (once with zinc twice with nickel gold) on arc splinters creates a suction effect quenching arc much faster than other mcbs -“action is a safe mcb”. mcb capacity includes 2amp to 63amp and also includes b & c series, sp, spn, dp, tp & tpn.
