APPLICATIONr
SWCPS series control and protective switch is suitable to the power distribution system of AC50Hz(60Hz),rated voltage 690V,rated current from 0.16 to 100A.Available for connecting,load bearing and breaking the current under the normal or not usually condition.
The use of environmental conditions:
Altitude: not exceed 2000m.
Ambient temperature: not higher than +40 °C, not less than -15°C
Can suffer the damp air.
No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
No rain or snow.
MAIN PARAMETERS
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;
