STM22-63 have protective function as shotrage as overload, and are used in lighting distribution systen in connerce and dwelling, and protrect fractional electric motors. and they also have many merits of high protective grade(up to IP20), high breaking capacity, reliable sensutive action, convenient, multi pole assemnling, long life ect. They are mainly adapted to the circuit of AC 50Hz, 250V in single pole, 415V in double, threee, four poles for protecting overload abd short circuit. Mean while, ther are also used in turning on or off the electric apparatus and lighting circuit under the normal conditions.
