Integrator note — 5SL4510-7CC
The Siemens SENTRON 5SL4510-7CC is a 1P+N miniature circuit breaker rated 10 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898 at 230 V AC. Neutral is switched internally, so the part covers both phase and neutral in a single 2-MW (36 mm) package.
Selectivity and coordination
Energy limiting class 3 means this MCB lets through less energy under fault, improving selectivity with downstream C-curve breakers of lower rating. The 10 kA SCCR at 230 V AC matches the typical service entrance rating for residential/infrastructure panels. For a BOM line requiring 10 A protection with neutral switching, the 5SL4510-7CC is the direct fit; the 5SL4120-7CC (same physical footprint, 2 MW, 1P+N) carries a 20 A rating with the same C-curve and 10 kA — the only difference is the overload threshold. No rewiring needed to swap between them at the same current level.
Panel integration
Snap-on DIN rail mount, 36 mm width (2 MW). Screw terminals accept 0.75–25 mm² solid or stranded conductors; torque to 2.5–3 N·m. Sealable (padlockable) for lockout/tagout. IP20 with conductors connected — suitable for enclosed distribution boards. Halogen-free and silicon-free construction for environments sensitive to outgassing.
