On the DC side it handles 15 kA at 60 V (72 V max), and for North American installs it carries a 5 kA SCCR under UL1077. Mounting position is unrestricted, and the sealable toggle accepts a padlock for lockout/tagout — handy when an MRO planner needs to isolate a circuit for line-down work. Rated IP20 with conductors connected, so it lives inside a closed enclosure, not in a washdown zone. ## Standards, approvals, and environmental limits This breaker carries triple-standard certification: IEC 60947-2 (the industrial standard for low-voltage switchgear), EN 60947-2 (European harmonized), and UL1077 (North American supplementary protector). That means it is accepted in panels destined for Europe, the UK, and North America without a separate component-level approval chase. Operating temperature spans -40 °C to 75 °C, with humidity derating: up to 95% RH at 55 °C, dropping to 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) means it holds up on a machine skid or near a conveyor drive without false trips. Halogen-free and silicon-free construction is a plus for clean rooms or coating lines where outgassing contaminants are a concern. Neutral conductor switching is not integrated (single-pole only), so the neutral bar stays separate. Rated for 50/60 Hz AC supply. Single-phase operation at 440 V AC, multi-phase at 440 V AC — so it handles 400 V line-to-line or 230/277 V line-to-neutral circuits common in industrial distribution. The 10 000 mechanical operating cycles typical service life means it will outlast most machine refreshes under normal switching duty.","metaTitle":"Siemens 5SY8106-7 SENTRON MCB, C-Curve 1P, 50 kA IEC","metaDescription":"Siemens 5SY8106-7 SENTRON miniature circuit breaker, 1-pole C-curve, 50 kA at 400 V AC per IEC 60947-2, 5 kA per UL1077.
