The Siemens SENTRON 5SL6320-7 is a 3-pole miniature circuit breaker rated 20 A with a C tripping characteristic, breaking 6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That 6 kA rating is the same under both standards — no split rating to track — so it coordinates cleanly in a residential or light-commercial distribution board where the upstream device provides the fault current ceiling.
IP20 with conductors connected — protected against finger contact in the enclosure but not against moisture, so it belongs inside a cabinet, not in a washdown zone. Sealable to prevent tamper, halogen-free and silicon-free for environments sensitive to outgassing.
