The Siemens SENTRON 5SV6016-6GV16 is an AFDD-MCB combination — an arc-fault detection device and miniature circuit breaker in one compact unit, rated 16 A, B-curve, with 6 kA breaking capacity per both EN 60898-1 and IEC 60947-2. It's a 1P+N (2-pole) design that fits a single 18 mm modular width on a DIN rail, so it drops into a standard residential or light-commercial distribution board without eating extra space.
Mounts on DIN rail (REG) in any position — no orientation restrictions.
That covers unheated utility rooms, outdoor-adjacent enclosures, and hot roof spaces.
