Still working on this quote for a customer and price seems to be the ONLY consideration. The maximum running current is stated at 45Amps. so I am thinking I will have to use an 80 amp circuit breaker. I was wondering with the part winding start if I could drop it to a 63 Amp D curve breaker. The reason is of course the difference in cable sizes your thoughts would be appreciated

The more bits you add on and multi cable runs, twin contactors and overloads, delay timer etc., the higher the install costs. Base the D curve breaker on LRA rating and overloads on FLA. Add and unloader head if power supply is a problem
