It delivers a 10 kA breaking capacity at 220 V DC per IEC 60947-2, which means it can safely interrupt a fault current of that magnitude without welding contacts or cascading failure upstream in the distribution panel. The B-curve trips between 3 and 5 times rated current, making it suitable for resistive or lightly inductive DC loads where inrush is minimal — think control transformers, solenoid valves, or DC power supplies — rather than motor circuits or capacitive loads that would nuisance-trip a B-curve. ## Mounting and panel fit Occupies 1 modular width unit (18 mm) on a DIN rail, with a quick-assembly fastening system that snaps onto the rail without tools. Depth is 76 mm, installation depth 70 mm, height 90 mm — standard SENTRON footprint that matches every other 1-pole 5SY series breaker in the same family. Mounting position is any orientation, which simplifies layout in tight enclosures. The IP20 rating applies with connected conductors, so it is suitable for enclosed distribution boards but not for wet or dusty environments without an outer enclosure. Combined terminals at both top and bottom accept the same conductor sizes as standard SENTRON breakers. Polarity must be observed — the supply connection position requires attention to polarity, unlike AC breakers where orientation is irrelevant. ## Environmental and compliance Ambient temperature range -40 °C to +75 °C. Humidity derating: max 95% at 55 °C, 55% at 70 °C, 35% at 75 °C. Pollution degree 3 and overvoltage category III. Halogen-free and silicon-free construction — relevant for clean-room or semiconductor-adjacent installations where outgassing can contaminate optics or sensitive surfaces. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. Supplementary devices (auxiliary switches, shunt trips, alarm contacts) can be installed on the side via the product extension feature, matching the same accessory range as other SENTRON 5SY breakers. The breaker is sealable for tamper-proof installations.","metaTitle":"Siemens 5SY5106-6CC SENTRON MCB, 1P B 6A 220V DC 10kA","metaDescription":"Siemens SENTRON 5SY5106-6CC miniature circuit breaker, 1-pole, B-curve, 6A, 220V DC, 10kA breaking capacity per IEC 60947-2.
