The DC rating of 15 kA per IEC 60947-2 covers battery-backed or rectified supplies up to 72 V. The 32 A rating derates with ambient temperature: 32 A at 45 °C, 31.33 A at 50 °C, 30.62 A at 55 °C. In a warm enclosure, factor that derating into the branch-circuit design. Snap-on DIN-rail mounting, any orientation. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) qualifies it for machine-mounted sub-distribution. ## Selectivity and coordination For UL 1077 / CSA C22.2 No. 235 installations, the breaking capacity is 5 kA — verify the label if the panel carries a dual rating. The C-curve selectivity with an upstream SENTRON fuse or molded-case breaker depends on the let-through energy; standard coordination tables from Siemens apply.","metaTitle":"Siemens 5SY8632-7 SENTRON MCB, 4P C-32A 30kA IEC","metaDescription":"Siemens 5SY8632-7 SENTRON 4-pole MCB, 32 A, C-curve, 30 kA IEC 60947-2 breaking capacity.
