Hi ram

The maximum start time varies from around 10 seconds to over 40 seconds depending on the motor design.

If you are looking fora safe value, then 10 seconds should be pretty safe with most motors that I have come across.
The big issue is whether this is long enough to start your load.

Best regards
Mark.
