The high strength miniature circuit breakers, which are housed in injection, molded flame retardant, high strength thermo plastic material having high melting point, high di-electric strength and temperature with stand. These are supplied under the brand name "Star". It has trip free mechanism, i.e., the breaker trips internally even if the operating knob is held in ON position. The tripping mechanism is thermal magnetic type. When overload values exceed the value specified for different characteristics curves i.e. B & C, strong magnetic field is induced which results into instantaneous tripping of M.C.B. Bi- metal which deflects if the current is greater than the rated current, so tripping the M.C.B. The contacts are made out of special alloy, which gives low contact resistance resulting in voltage drop hence very less power consumption and temperature rise. These contacts have very excellent anti weld properties.
