SZM1E series Molded Case Electronic Circuit  Breaker (hereafter referred to as simply breakers)  are  one  of the new type  breakers which have been developed by the company using international advanced design and manufacturing technology. The rated insulation voltage of the breakers is 800V, suitable for turn-on or turn-off not frequently and starting a motor not frequently in the circuit of AC50Hz, rated working voltage  690V or below rated working current up to 800A. The breakers have  overload, short-circuit and under voltage protection devices. so as to protect  the circuit and the power equipment against damage.Short circuit short delay time definite time, short circuit instantaneous and undervoltage protection function and residual current protection (optional), phase failure protection function (optional), can short-circuit short delay time inverse time, Protection circuit and power equipment from damage, circuit breaker protection features complete, accurate, can improve the reliability of power supply, to avoid unnecessary power outages, including "Z, B" type control with communication interface can be "four remote" Meet the requirements of control centers and automation systems.


The breakers according to the rated maximal value to short- circuit breaking ability (Icu), would be classified four kinds types C (basic type), L (typica1 type), M (second high breaking type) and  H (high breaking type). The breakers are of the following characteristics: compact size, high breaking ability, short arc-over distance (some of the "0" arc-over distance) and shake proof. They also undergo the tests of nuclear industry conditions (1E grade) and ship conditions, and become the only product using in nuclear industry base among the same products made in the country, further more become the ideal products applied on land or ships.
