It occupies 4 modular-width units (72 mm) on a DIN rail, making it a standard fit for distribution boards and control panels where short-circuit and overload protection of final circuits is required. ## What the ratings mean for fit The C characteristic (tripping between 5 and 10 times rated current) suits circuits with moderate inrush — motor starters, transformers, or groups of LED drivers — where a B curve would nuisance-trip but a D curve would delay too long. The 10 kA breaking capacity at 400 V AC matches the majority of commercial and industrial panel SCCR requirements; if your facility needs UL 1077 recognition, the same part is rated 5 kA per UL 1077 and CSA C22.2 No.235. At 72 mm wide (4 MW) and 76 mm deep, it drops into any standard 35 mm DIN-rail enclosure with 70 mm installation depth. The IP20 rating with connected conductors means it's for enclosed panels only — not for wet or outdoor standalone use. ## Panel integration and compliance Mounts in any position on a 35 mm DIN rail via the quick-assembly system. Both top and bottom terminals accept combined conductors (busbar and wire). The housing is halogen-free and silicon-free — relevant for clean-room or high-reliability environments where outgassing matters. Sealable covers are available as an accessory for tamper-proofing. Supplementary devices (auxiliary contacts, shunt trips, alarm switches) can be installed on the side, which is useful for remote status indication or emergency-off integration without adding a separate contactor.","metaTitle":"Siemens 5SY4432-7CC SENTRON 4P C-Curve MCB, 10kA, 400V","metaDescription":"Siemens 5SY4432-7CC SENTRON 4-pole miniature circuit breaker, C-tripping characteristic, 10 kA breaking capacity per EN 60898 at 400 V AC.
