The 5SQ2360-0KA13 is a 3-pole miniature circuit breaker rated 13 A at 400 V AC, 50 Hz, with a B tripping characteristic. Overvoltage category 3 and energy limiting class 3 align with distribution board use — it limits let-through energy for downstream equipment protection.
Deployment context
The 55 mm installation depth and 3 width units fit standard DIN-rail enclosures. The neutral conductor is not switched, so it's a 3-pole breaker for a 3-phase supply without neutral protection.
