i have a problem that every 5 or 10 minutes my pump stops
i have a ABB B9-30-10 Contactor
and a ABB T25 THERMAL OVERLOAD RELAY
when this happends all electricity is still working
but the ABB B9-30-10 Contactor switches off
i assume this is because of the ABB T25 THERMAL OVERLOAD RELAY?
there is a volt and some other things you can turn on front of the ABB T25 THERMAL OVERLOAD RELAY, and then it will work for another 5 or 10 minutes
i connected the pump directly to the 220volt, and thats been running perfect
so what could be the problem?
could the ABB T25 THERMAL OVERLOAD be bad?
any input is welcome
