AC Fire CPS Control and Protective Switching 0.4A-45A 3p GNK8 serices CPS
APPLICATION
GNK8 control and protective switch is suitable to the power system of AC50/60Hz,rated voltage max690V,rated currentfrom 1A to 100A,used to connect ,load and break normal and set improper current.GNK8 is a switch that combine the function of circuit breaker, contactor, thermal relay etc. each feature coordinate inside .When it is applied in 3 phase AC motor ,it can protect the circuit from phase loss, over voltage,under voltage and 3 phase imbalance. GNK8 is operated by itself and manual and can achieve automatically control remotely and direct manual operation.
GNK8 control and protective switch can be divided as Y type (normal breaking capacity),) type (high breaking capacity),H type (highest breaking capacity)
GNK8 installation can be vertical and level;
GNK8 conform the standard:lEC60947-6-2

PARAMETERS
Overload long time delay protection: the user can set by himself, the default value is Ir1=1.5le,breaking time<10s;
Short circuit short time delay protectionar2=6-121e,the default value for motor is Ir2=121e, Ir2=61e for power distribution;
Short circuit instant protection:lr3=8-16le ,the default value Ira=14le±20% breaking time<=0.2s;
Time delay protection when start: during the starting, the switch only protect the equipment from phase loss, over-under voltage, short circuit, current leakage and tri-phase imbalance and the breaking time <=5s;
Over voltage protection: when the working voltage exceed the default set value,he breaking time <=10s;
Under voltage protection: when the working voltage is below the default set value,the breaking time <=10s;
Phase loss protection: when any of the phase is lose ,the breaking time is <=3s;
Tri-phase imbalance protection: when the current difference between any phase is 20--80%(default 60%),the breaking time <=10s;
Under current protection: when the working current is below the default set current,the breaking<=30s;
Current leakage protection: when the leakage current is larger than the set value,the breaking time <=0.2s;
