reffered 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 CM l 63 is 400V rated working current up to 800A CM1 800 is motor protection free The breakers have overload short circuit and under voltage protection devices so as to protect the circuit and the power equipment against damage The breakers according to the rated maximal valueo 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 the0arc over distance and shakeproof 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 furture more become the ideal products applied on land or ships The breakers could beinstalledvertically upright or horizontally transverse The breaker has disconnecting function its corresponding symbol is shown as The breakers comply with the demands of the following standards IEC60947 1 and GB 14048 1 2006General rules IEC60947 2 and GB14048 2 2008circuit breakers IEC60947 4 1 and GB14048 4Electromechanical contactors and motor starters IEC60947 5 l and GBl4048 5Electrical equipments of electromechanica1 control circuit The breaker is permitted to use the CCC marking of CQC and CE marking issued by TUV Rheinland of Germany t 适用范围
