PARAMETERS
Overload long time delay protection: the user can set by himself, the default value is Ir1=1.5le,breaking time<10ق;
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;
