The 10 kA breaking capacity at 400 V AC is the figure that governs fault clearance under the EN 60898-1 standard — it means this MCB safely interrupts a short-circuit current up to 10,000 A without welding its contacts or rupturing the case. For DC circuits, the 15 kA rating at 60 V (max 72 V operating) covers battery-backed control buses and solar combiner boxes. The dual-standard listing (IEC 60898-1 for residential/commercial distribution, IEC 60947-2 for industrial switchgear) gives the 5SY4180-6 a wider compliance envelope than a domestic-only MCB; it is accepted in both a lighting sub-panel and a machine control cabinet. The B-curve avoids nuisance tripping on cable charging currents but still clears a hard fault fast enough to protect downstream wiring. The 18 mm width (1 modular unit) and 70 mm installation depth leave room for adjacent devices in a crowded enclosure. The halogen-free and silicon-free construction matters in environments where outgassing during a fault could corrode nearby contacts or contaminate clean-room air. Ambient operating range spans -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C).","metaTitle":"Siemens 5SY4180-6 SENTRON MCB, 1P B-Curve, 10kA IEC","metaDescription":"Siemens 5SY4180-6 SENTRON miniature circuit breaker, 1-pole B-curve, 10 kA per IEC 60898-1, 15 kA DC per IEC 60947-2. 18 mm wide, halogen-free, active production.
