The Siemens 5SN4506-7CN is a SENTRON miniature circuit breaker rated 6 A with a C tripping characteristic, 1P+N pole configuration, and a 10 kA breaking capacity per EN 60898 at 230 V AC.
The 1P+N design switches the line conductor and switches the neutral — the neutral is not protected but is disconnected when the breaker trips, which is common for single-phase final subcircuits in many regional standards. It accepts solid conductors up to 25 mm², so it handles the feed-through wiring for downstream loads without needing a separate terminal block.
Halogen-free and silicon-free construction, sealable for tamper-proofing in metered installations.
