The Siemens SENTRON 5SY6106-8CC is a 1-pole miniature circuit breaker with a D tripping characteristic, rated 6 kA breaking capacity per EN 60898 at 400 V AC. It's built for industrial panel applications where the load draws a heavy start-up surge.
That 18 mm width keeps the panel dense — you can pack 16 of these in a standard 300 mm DIN rail section.
Rated for a wide ambient temperature range: -40 °C to 75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, stepping down to 35% at 75 °C). That makes it usable in unheated outdoor cabinets or near hot machinery. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — solid for installation on a conveyor line or pump skid. Halogen-free and silicon-free construction reduces corrosion risk in sealed enclosures.
