The Siemens 5SY3006-7KV26 is a 1+N-pole miniature circuit breaker rated 230 V with a 4.5 kA breaking capacity, C-curve 6 A, neutral on the left, and a 70 mm depth. The neutral-left configuration matters when replacing a unit in a panel where the busbar or wiring order assumes neutral on the left side; swapping to a neutral-right breaker means re-dressing the tails.
Mounts on standard DIN rail. The 70 mm depth fits most enclosure depths without crowding the gland plate or door clearance. Neutral-left orientation matches the typical European panel layout where the incoming neutral bar sits on the left side of the DIN rail.
