The 3P+N configuration switches the neutral conductor, so it's ready for single-phase or three-phase loads where you need the neutral opened and closed with the poles. ## What the breaking capacities mean for your panel The 25 kA under IEC 60947-2 is the industrial rating — that's the number that matters when this breaker sits downstream of a larger transformer or in a high-fault industrial panel. The 5 kA UL 1077 rating means it's recognized as a supplementary protector in UL 508A industrial control panels, not a branch-circuit protective device under UL 489. If your BOM calls for UL 489, this isn't the part; if it's a UL 508A panel, the 5 kA supplementary rating works. Mount in any position. Rated IP20 with conductors connected, so it's for inside an enclosure, not a washdown zone.","metaTitle":"Siemens 5SY7620-6 SENTRON MCB, 4P, B-Curve, 400 V AC, 15/25","metaDescription":"Siemens 5SY7620-6 SENTRON 4-pole miniature circuit breaker, B-curve, 400 V AC, 15 kA (EN 60898) / 25 kA (IEC 60947-2).
