What circuit breaker is recommended for ATV58HD64N4XZU?

The circuit breakers specified in the ATV58 Installation Guide provide branch short circuit protection. Because circuit breakers are typically slower than fuses, they are not as effective in limiting damage in the event of an internal drive short circuit such as shorted bus connections, shorted input rectifier, or failure of the internal solid state overcurrent protection circuit in the drive controller.

For CT, CTLN or VTLN, the recommended circuit breaker size is 150.
For VT applications the recommended size is 200 amp.
Use SquareD KAL or equivilant type breakers.
