It delivers a 25 kA breaking capacity per IEC 60947-2 — that is the rating that governs fault clearance in industrial panel feeders, not the lower 5 kA per UL 1077. For a 4-module-width DIN-rail unit, that is serious fault-interruption headroom for motor control centers or distribution sub-panels. The 25 kA at 400 V AC per IEC 60947-2 is the design-basis rating — this breaker can safely interrupt a fault current up to that level without welding contacts or cascading upstream. The UL 1077 / CSA C22.2 No. 235 listing at 5 kA is a separate supplementary-protector rating for North American panels. Accepts combined terminal top and bottom for daisy-chaining busbars. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — fine for machine-mounted sub-panels. Halogen-free and silicon-free construction. Operates from -40 °C to 75 °C ambient, with humidity derating above 55 °C. Sealable for tamper-proof applications.","metaTitle":"5SY7432-7CC SENTRON MCB 4P C-curve 32A 25kA","metaDescription":"Siemens SENTRON 5SY7432-7CC miniature circuit breaker, 4-pole, C-curve, 32A, 25kA per IEC 60947-2.
