Product Description
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 standardsIEC 60947-1 and GB/T14048.1-2000 generalIEC 60947-2 and GB/T14048.1-2001 low voltage breakersIEC 60947-4-1 and GB/T14048.4-2003 mechanical contactors and motor startersIEC 60947-5-1 and GB/T14048.5-2001 electrical equipments of electromechanical control circuit
The rated insulation voltage of this Circuit Breaker is 750V which is applicable for theelectricity distribution net of AC 50Hz, rated working voltage 690V and below, rated workingcurrent from 6A to 630A. It is used to distribute electric power and protect the line and poweapparatus from being overload and short-circuit protection of the motor.This circuit breaker can be installed vertically and horizontally.This product complies with standard IEC60947-2.GB14048.2
