The 1P+N configuration switches the line conductor and provides a switched neutral, common in single-phase final subcircuits. The C8 tripping characteristic (8 A rated current, C-curve) means it holds up to 5–10× In for short overloads, suited to moderate inrush loads like small motors or lighting banks where nuisance tripping from a standard B-curve would be a risk. ## Deployment context Snap-on DIN-rail mounting for panel integration; the 1P+N width occupies two modular spaces (36 mm) on the rail, which matters for fill-factor planning in a crowded enclosure.","metaTitle":"Siemens 5SY4508-7CV MCB, 15kA Icu 230/400V 1P+N C8","metaDescription":"Siemens 5SY4508-7CV miniature circuit breaker, 15kA Icu at 230/400V, 1P+N, C8 curve.
