The Siemens SENTRON 5SY4632-7 is a 4-pole miniature circuit breaker (3P+N) with a C tripping characteristic, designed for final-distribution and industrial control panels per IEC/EN 60898-1 and IEC 60947-2 / UL1077. Rated breaking capacity is 10 kA under IEC/EN 60898-1 and 20 kA under IEC 60947-2; at DC (per IEC 60947-2) it handles 15 kA up to 72 V. That dual rating means it qualifies for both residential and industrial coordination studies.
Mounting position is any orientation; IP20 with conductors connected, so it lives inside a panel enclosure. Neutral conductor is switched (4-pole), so it disconnects the neutral alongside the phases — required in TN-S or TT systems where neutral isolation matters. Installation depth is 70 mm (device depth 76 mm). Halogen-free and silicon-free construction, sealable for lockout/tagout.
Humidity derating applies above 55 °C: max 95% RH at 55 °C, tapering to 35% at 75 °C. Energy limitation class 3 means fast arc extinction, limiting let-through energy to downstream equipment.
