Hi friends The time required for switching the integrated bypass contactor depends on the type of load we are using like crushers,blower,conveyors etc generally we set start time in between 10sec to 15sec after the start is over bypass contactor pick up. Yes it depends on particular operation but for few second. regard aakash

My question was what is the time needed for contact to switch (in miliseconds), when starting time is finished, not what is required setting the starting time. I hope you can provide me this info.
