Intelligent Motor Protector

1.Starter protection: When stares, it can protector motor from phase failure, over-voltage, under-voltage,short circuit ,and three phase unbalance, etc.
2.Over-current protection: over-current motion time is anti-time limit protection, The
motion time is set by user
3.Under-current protection: When working current is seriously low than set under-current, the motion time shorter than 10s
4.Phase failure protection: When any phase failure ,motion time shorter than 2.0s
5.Block stopping protection: When working time is 3-8 times of set current .motion
time shorter than 1.0s
6.Over-voltage protection : When the working voltage is higher than the set over-voltage,motion time isshorter than 30s
7.Under-voltage protection: When the working voltage is lower than the set under-voltage,motion time is shorter than 30s
8.Unbalance protection: When the current difference higher than 60% between any two phase, motion time is lower than 2.0s
9.Short circuit protection: when working current is 8 times or more than set current, motion time is shorter than 0.2s
10.Automatic starter function: When use this function, the user should set the automatic start time, at this time can not starter communication
11.There is indicate light, For indicating the current and fault sort

The above functions are the basic functions. We can still add the creepage function, earthing function, thermal protection, time protection and star-delta change function
