The Siemens SENTRON 5SY4232-7KK11 is a 2-pole miniature circuit breaker with a C-curve tripping characteristic, rated at 32 A. It is designed for railway applications and carries a breaking capacity of 10 kA per EN 60898 and 20 kA per IEC 60947-2, giving you the higher fault-current rating for industrial panel coordination.
The rated current derates with ambient temperature: 30.46 A at 40 °C, 29.66 A at 45 °C, 28.86 A at 50 °C, 28 A at 55 °C, and 27.14 A at 60 °C — factor this into your enclosure thermal budget.
