The Siemens 5SY4332-7CV is a 3-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 32 A at AC and a breaking capacity of 15 kA per IEC 60947-2.
At 35 °C ambient the breaker carries its full 32 A. At 40 °C it derates to 29.66 A, at 45 °C to 28.42 A, at 50 °C to 27.1 A, and at 55 °C to 25.73 A. The 3-pole unit occupies 3 modular width units (54 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth) and mounts in any position via the quick-assembly system onto standard DIN rail. IP20 with connected conductors, pollution degree 3, overvoltage category III — it's built for the inside of a control cabinet, not for wet environments.
