[QUOTE="Sidewinder, post: 539648, member: 9512"] I wouldn't bet on it! A motor overload upstream of a VSD doesn't operate as a motor overload. The drive controls and limits the motor current. There are circuit breakers which look like a motor overload specifically for such applications, though. An overload between the drive and motor is very unusual and not acceptable with some drives. It is most commonly seen with one drive and multiple motors connected to it. Some drives do not allow an isolator between drive and motor as the drive outputs would be open circuited and that is an issue in some drive designs [/QUOTE]
