It's designed for DC circuits up to 250 V maximum, with a breaking capacity of 10 kA at 220 V DC. This is a 1-module-width (18 mm) unit that snaps onto a DIN rail via the quick-assembly system. Its IP20 rating with connected conductors means it's intended for enclosed distribution boards or control cabinets — not exposed outdoor mounting. The operating temperature range spans -40 °C to 75 °C, with a derating curve that drops the continuous current from 16 A at 35 °C to 13.1 A at 55 °C. ## DC ratings and what they mean for fit The 10 kA DC breaking capacity at 220 V is the headline number for DC applications. DC arcs are harder to extinguish than AC — they have no zero-crossing — so this rating tells you the breaker can safely interrupt a fault up to 10 kA on a 220 V DC bus. The maximum operating voltage is 250 V DC, so it covers nominal 220 V DC systems with headroom. For DC circuits, polarity must be observed on the supply connection. ## Integration and panel fit Mounts in any position on a standard 35 mm DIN rail. The 18 mm width (1 modular unit) means it occupies a single slot in a distribution board. Depth is 76 mm, installation depth 70 mm — check your enclosure's door clearance if using a transparent cover. The combined top and bottom terminals accept the same conductor sizes; the breaker is sealable for tamper-proof installations. It's halogen-free and silicon-free, which matters for panels in clean-room or high-value electronics environments where outgassing can cause contact corrosion.","metaTitle":"Siemens 5SY5116-7CC SENTRON MCB, 16A C-Curve, 1P, 10kA DC","metaDescription":"Siemens SENTRON 5SY5116-7CC miniature circuit breaker, 16A rated at 35°C, C tripping characteristic, 1-pole, 10kA DC breaking capacity at 220V.
