Answer Posted / sunthosh080
usually when you see the relay technical details there will
CLASS type (5-30)
When your motor is taking 6 times for 5 sec you have to
select 5. So that your relay doesnt trip during this and it
depends on the application also.
If it fan application , then it would be around 15-20.
If the relay is tripping during motor starting then it
CLASS problem.
