The D curve (10–20× In) is the key spec: it handles inrush from motor loads, transformers, and power supplies without nuisance tripping — unlike a B or C curve, which would trip on the same surge. At 25 A, this breaker suits a 7.5 kW motor on 400 V three-phase or a cluster of smaller inductive loads. Breaking capacity: 6 kA at 400 V AC per EN 60898 covers most industrial distribution boards; the 5 kA UL 1077 rating confirms it for North American panel use where the available fault current is under that level. Snaps onto a DIN rail (quick-assembly system) and needs 36 mm width — two 18 mm width units. Terminal design allows combined top and bottom feed, and the sealable cover satisfies lockout/tagout requirements on the line.","metaTitle":"Siemens 5SY6225-8CC SENTRON MCB, 25 A, D Curve, 2-Pole, 6 kA","metaDescription":"Siemens 5SY6225-8CC SENTRON miniature circuit breaker, 25 A rated current, D tripping characteristic, 2-pole, 6 kA breaking capacity per EN 60898.

The difference is the tripping curve — 5SY6225-8CC is D-curve (10–20× In), while 5SY3132-6 is a different characteristic. Check the existing breaker's curve before swapping; if the original was also D-curve, it drops in without rewiring."},{"question":"What compliance documentation does Siemens provide for 5SY6225-8CC?","answer":"The breaker carries UL 1077 and CSA C22.2 No. 235 certification, plus CE marking.
