The 15 kA rating per EN 60898-1 is the residential/light-commercial benchmark; the 25 kA rating per IEC 60947-2 is the industrial-installation figure that matters for coordination studies in a 400 VAC panel. At DC the breaker is rated 15 kA per IEC 60947-2 up to 72 V. Four poles with no neutral switching — this is a straight 4-pole line-side disconnect for three-phase loads where the neutral is solidly bonded downstream, not switched. The 4 MWU footprint occupies 72 mm of DIN rail, standard for a 4-pole MCB in this class. Dual-classified under IEC/EN 60898-1 and IEC/EN 60947-2 / UL1077. The UL1077 listing means it is recognized as a supplementary protector in North American panels — not a branch-circuit rated breaker per UL 489, so verify the application code before specifying for UL 489-only jobs. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SY7432-7 SENTRON MCB, 4P C-curve, 15kA/25kA","metaDescription":"Siemens 5SY7432-7 SENTRON 4-pole miniature circuit breaker, C-curve, 15 kA per EN 60898-1 / 25 kA per IEC 60947-2.
