KNM1 series moulded case circuit breaker(hereafter reffered to as simply breaker) The rated insulation voltage of the breaker is 800v (KNM1-63 is 500v),suitable for turn-on or turn off not frequency and starting a motor not frequently in the circuit of AC 50hz,rated working voltage 690V or bellow (KNM1-63 is 400v)-rated working current up to800A (KNM1-800 is motor protection-free), The breakers have overload, short -circuit andunder voltage protection devices, so as to protect the circuit and the power equipment against damage.Breakers could be installed vertically(upright) or horizontally (transverse);
Breakers has disconnecting function, its corresponding symbol is shown as “fuhao”;
Breakers comply with demands of following standards
IEC60947-1 and GB/T14048.1-2000 general
IEC60947-2 and GB/T14048.1-2001 low voltage breakers
