The Siemens 5SV6016-7KK10 is a SENTRON-series AFDD-MCB combination unit — an arc-fault detection device and miniature circuit breaker in one compact housing, 1 MW (18 mm) wide for DIN-rail mounting. It protects a 230 V AC, 10 A final circuit with a C-curve tripping characteristic and a 6 kA breaking capacity rated per both EN 60898-1 and IEC 60947-2. The arc-fault detection function distinguishes dangerous series and parallel arcs from normal switching transients, so it goes into circuits where a plain MCB alone wouldn't catch a smoldering connection — think residential final circuits, hotel rooms, or student housing where the risk of loose terminations or damaged cords is higher.
Snaps onto standard DIN rail (EN 60715), occupies 1 modular width unit (18 mm), and accepts supply from either side — no forced orientation. Depth is 68.5 mm, installation depth 70 mm, so it clears a 100 mm deep enclosure with room for wiring. Ambient range is -40 °C to 75 °C, with 55 °C at 95% relative humidity — fine for an unconditioned electrical room or outdoor-rated enclosure.
The 6 kA breaking capacity at 230 V AC is the same figure under both EN 60898-1 (the residential MCB standard) and IEC 60947-2 (the industrial breaker standard). At 10 A rated current, the power loss per pole is 1.66 W in hot operating state — negligible for thermal budgeting in a multi-way consumer unit.
Halogen-free and silicon-free construction, which matters for clean-room or high-reliability installations where outgassing can't contaminate optics or contacts. The product designation as an AFDD-MCB combination means it carries the relevant IEC/EN standards for both functions — arc-fault detection (IEC 62606) and overcurrent protection (EN 60898-1 / IEC 60947-2).
