The Siemens SENTRON 5SY4225-6CC is a 2-pole miniature circuit breaker rated 25 A at 400 V AC with a B-curve tripping characteristic. It interrupts fault currents up to 10 kA per EN 60898, and carries a 5 kA rating under UL 1077 and CSA C22.2 No. 235 for North American panels. The B-curve (3-5 In) is the standard choice for residential and light commercial lighting and socket-outlet circuits — it trips fast enough to protect 2.5 mm² wiring but avoids nuisance tripping on moderate inrush from small motors or transformers.
