The Siemens SENTRON 5SL4601-7CC is a 4-pole miniature circuit breaker (3P+N) with a C tripping characteristic, rated 1 A at 400 V AC.
The 4-pole (3P+N) configuration switches all three phases and the neutral. The neutral pole is switched but not protected — it opens and closes with the phases but has no overcurrent trip. This is the common arrangement for TN and TT systems where you want to isolate the neutral during maintenance. Terminals accept 0.75 to 25 mm² — enough for the incoming feed and outgoing sub-circuits.
Any mounting position is permitted. Halogen-free and silicon-free construction — no corrosive off-gassing in a fire, which matters for equipment rooms with sensitive electronics or where smoke toxicity is a concern.
