6. Protection Functions and theirs explanation

We make our soft starters have all kinds of protection functions to protect the soft
starter and the motor using. Please choose the correct Protection class and
parameters according to your usage conditions!

Over-heat Protection

：

when the temperature inside soft starter is up to 80

℃±

5

℃

,the starter will be into Over-heat protection, when be down to 55

℃

,this

protection removes.

○

Input failure-phrase protection: the delayed time

＜

3s

○

Output failure-phrase protection: the delayed time

＜

3s

○

Three-phrase unbalanced protection: the delayed time

＜

3s,when the different

current value among three phrases is more than 50%±10%,the protection be
used.

○

Starting over-current protection: the diagram 6.1 shows the protection time

when the Current is more 5 times than the rated working current.

○

Working over-load protection: the starter will be in inverse time thermal

protection on
Base of the Max working current of motor (Set by F6 Item), (The diagram 6.1 s
