Sphere of application
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
