I have a customer that wants to use Circuit Breakers only. Their panel is a single VFD and a control transformer for the 120vac controls. We need to achieve a SSCR of 30KA. Any suggestions on what to use for a Circuit Breaker on the primary side of the control transformer. I have always used a set of fuses and the circuit breakers all have a SSCR of 5 to 10 KA.
