The Siemens 5SY7225-7CC is a 2-pole SENTRON miniature circuit breaker with a C tripping curve, rated 25 A at 35 °C and 440 V AC multi-phase.
Mount in any position. IP20 with conductors connected — standard for enclosed distribution boards. Derating is baked in: 25 A at 35 °C drops to 23.18 A at 40 °C, 22.2 A at 45 °C, 21.18 A at 50 °C, and 20.1 A at 55 °C.
Current-production part. No successor or phase-out notice on record.
Both are 2-pole SENTRON MCBs on the same DIN-rail footprint (2 MW wide), so the mechanical fit is identical. The difference is electrical: 5SY7225-7CC carries a 25 A C-curve with 25 kA breaking capacity, while 5SY4125-7CV is a different rating — verify the load current and fault level before swapping.
