Zusammenfassung:PURPOSE: An instantaneous trip device of a small circuit breaker is provided to change an operating current of an operating core by installing an adjusting lever for randomly changing elastic force of a spring. CONSTITUTION: An instantaneous coil assembly(100) is composed of a bobbin(110), a coil(120), a fixing core(130), and an operating core(140). The coil generates magnetic force proportional to the amount of currents on a circuit. The fixing core is combined with a side of the bobbin to be magnetized by the magnetic force of the coil. The operating core performs sliding movement to the fixing core by the magnetization. An adjusting unit(200) is composed of an adjusting spring(210) and an adjusting lever(250). The adjusting lever is composed of a first adjusting panel(260) and a second adjusting panel(270).
