The maximum input current of the PXB series is as follows:

• 10 kW models: 40 A (200 Vac input), 20 A (400 Vac input)
• 20 kW models: 80 A (200 Vac input), 40 A (400 Vac input)

Select a circuit breaker with a current rating that provides sufficient margin for the maximum input current of the applicable model. For example, if the maximum input current is 80 A, consider using a 100 A rated circuit breaker. To support both sourcing and regenerative operation, use a time-delay Residual Current Circuit Breaker (RCCB) that is compatible with reverse connection.

For details, refer to "Input Specifications" in the User's Manual.
