Focus on decentralization?
FIEPOS eFused is the right choice.
The PISA-B units are IP20 electronic circuit breakers meant to distribute the current to several loads in one central protected spot - like a cabinet.
IP54, IP65/IP67 field power supplies, designed to power and protect decentralized loads directly in the field - outside of a protected cabinet. It includes up to 4 current-limited outputs for selective current distribution, a variety of plug connectors and IO-Link as a communication interface.
So FIEPOS eFused and PISA-B share some essential features, but are designed for different applications. Ultimately, your individual application determines which solution is right for you.
