c. Phase lack protection
:
when any phase current lacks phase, the acting time
≤
2s
;
d. Imbalance protection
:
when the difference between two phase reach 60
~
75% , the acting time
≤
5s
;
e. As for the protecting characteristic of overloading inverse time lag (time unite is second), please see the
below form. Multiple
=
I actual value
/
I set value.
When the motor running current is more than or equal to 1.2 times the current set to 3.0 times, deferred
action according to the overloaded multiple and actuation in below table
