The 5SY4315-7: The breaker is rated IP20 with connected conductors and includes integrated touch protection on the terminals, which means it can be installed in open panel sections without additional finger-duct covers as long as the wiring is terminated.
The enclosure is halogen-free and silicon-free, which is a requirement for certain clean-room or marine applications where outgassing from the plastic could contaminate sensitive equipment.
