The series switch belongs to the 21st century whole world advanced level electric appliance product. They have protective functions against short circuit and overload, and are used in lighting distribution system in industry, commerce and dwelling, and protect fractional electric motors. They also have many merits of high breaking capacity, good reliability of sensitive action, convenient multi-pole assorting, long using life etc. They are mainly adapted to the circuit of AC 50/60Hz, 230V in single pole, 400V in double, three or four poles for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition. The products are produced according to IEC60898. IEC60947.
