What it is and what it does
The Siemens SENTRON 5SV6016-7KP06 is an arc-fault detection unit (AFDD) combined with a miniature circuit breaker (MCB) — a single 2-pole device that detects both series arcs (e.g., a loose terminal or damaged conductor) and parallel arcs (line-to-neutral or line-to-ground faults) and interrupts the circuit. It is rated 6 A at 230 V AC, with a C-curve tripping characteristic and a 6 kA breaking capacity per EN 60898. The series arc detection range is 1 A to 6 A; parallel arc detection covers 50 A to 500 A.
Where it belongs in the panel
Snaps onto DIN rail (REG) and occupies a single modular width unit (18 mm wide, 90 mm tall, 68.5 mm deep). The 70 mm installation depth fits standard distribution boards. Mounting position is unrestricted — any orientation works. The IP20 rating applies with conductors connected; keep it inside an enclosed panel or consumer unit.
What the ratings mean for fit
The 6 A rated current and C-curve make this unit suited for final circuits supplying general-purpose loads like lighting, socket outlets, or small appliances where inrush currents are moderate. The 6 kA breaking capacity is the standard for residential and light commercial distribution boards per EN 60898. The arc-fault detection function adds a layer of protection against electrical fire hazards — series arcs down to 1 A and parallel arcs up to 500 A are within its detection envelope.
