It breaks 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — enough for residential and light commercial distribution boards where the prospective fault current stays under that ceiling. C-curve trips between 5× and 10× In (50–100 A for this 10 A unit). That suits mixed loads with moderate inrush — lighting banks, small transformers, contactor coils — where a B-curve would nuisance-trip on startup but a D-curve would let a sustained overload run too long. The 4.5 kA breaking capacity per EN 60898 is the standard domestic rating; the 5 kA per IEC 60947-2 gives a small margin for industrial panel coordination. If your distribution board's SCCR exceeds 5 kA, step up to the 5SL series' 10 kA variants. Single-pole switching, 250 V phase-to-neutral or 400 V phase-to-phase (single-phase operation). Rated for 50/60 Hz supply. The 72 V DC maximum means it can also protect DC control circuits — common in 48 V or 60 V telecom/battery-backed loads — but verify polarity and arc extinction for DC use. Occupies 1 modular width unit (18 mm) on standard DIN rail. IP20 with connected conductors, so it belongs inside a panel, not exposed to washdown. Sealable, halogen-free, silicon-free — relevant for clean-room or food-bev zones where outgassing or contamination is a concern.","metaTitle":"Siemens 5SL3110-7 SENTRON MCB, 1P C 10A, 4.5kA","metaDescription":"Siemens 5SL3110-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 A, 4.5 kA per EN 60898.
