The D tripping characteristic means it tolerates brief inrush currents up to 10–20× rated current before tripping — sized for loads like small transformers or solenoid valves that pull a heavy start surge. At 0.3 A, that's a 3–6 A inrush headroom for a few cycles. Wire terminations accept solid or stranded conductors from 0.75 to 25 mm², torqued to 2.5–3 N·m. For BOM traceability, the manufacturer provides compliance documentation including RoHS and REACH declarations. The part carries a touch-protection feature and is sealable for tamper-proof installations. The 18 mm width (one module) fits standard enclosure cutouts. Overvoltage category 3, pollution degree 3 typical for fixed-installation switchgear. ## Electrical ratings and selectivity Single-pole switching at 400 V AC phase-to-neutral, with a maximum multi-phase operating voltage of 440 V AC. The D-curve and energy limiting class 3 give it a defined let-through energy profile for selective coordination downstream.","metaTitle":"Siemens 5SL4114-8 SENTRON MCB, 1P D-curve 0.3 A, 10 kA","metaDescription":"Siemens 5SL4114-8 SENTRON miniature circuit breaker, 1-pole, D characteristic, 0.3 A rated, 10 kA breaking capacity per EN 60898.
