ECN Forum Forums General Topics of the Trade General Discussion Area Disconnect on the secondary of a VFD

If the breaker was located between the VFD and the motor, damage could be a possibility.

Every VFD installation I have seen has the overcurrent protection on the line side of the VFD, though. Interrupting the AC feed to the VFD isn't a problem, but you don't want to break the OUTPUT leads.
