Hello,

I am working on a project that needs to automatically stop 3 phase motor, through a DOL starter. The signal from the controller is given to a relay to stop the motor. A NC relay in series with the starter coil will do the job. but im not sure of the rating of the relay to be used.

Hence i need to know (i) The current rating of Coil of a DOL starter operating at 415V and (ii) The relay contact current rating that can be use.

Presently i have designed the relay with contact rating of 10 A ....

Do help me ASAP... Thanks in advance !!
