The Siemens 5SY4325-8CC11 is a 3-pole miniature circuit breaker from the SENTRON series, rated 25 A with a D tripping characteristic. It breaks 10 kA at 400 V AC (per EN 60898) — that's enough to handle moderate fault levels in industrial and railway distribution panels without upstream reinforcement. The D curve means the magnetic trip holds off inrush from motor loads and transformers; expect it to tolerate 10–20× rated current briefly before snapping open.
