The Siemens 5SY3008-7KL is a SENTRON miniature circuit breaker (MCB) with 1P+N poles, C-curve tripping characteristic, and an 8 A rated current at 230 V AC. It breaks faults up to 4.5 kA per EN 60898 — that's the standard for household and similar installations, so this part is sized for final subcircuit protection in distribution boards, not main incoming feeders. The 1P+N configuration switches both phase and neutral, with the neutral pole switching but not protecting (no overcurrent release on N).
The IP20 rating applies only with connected conductors, so the busbar and wiring must be in place to maintain the protection level. Terminal torque range is 17.7 to 22.1 lbf·in — a standard screwdriver setting for this class.
