Sizing and selectivity for the panel schedule
The S802S-B32 is a 2-pole miniature circuit breaker rated at 32 A with a Trip Curve B characteristic, meaning it trips at 3–5 times rated current — suited for resistive or lightly inductive loads where inrush is low. The 50 kA interrupting rating at 230 VAC gives you headroom for high-fault-capacity installations, like main distribution panels or sub-feeds close to a transformer. Mounts on standard DIN rail; plan for the 2-pole width in your enclosure fill.
