The device is instantaneous, so it trips without intentional delay, and its energy limiting class is 3, which limits let-through energy during a fault. The ambient temperature range is -25 to +45 °C, and derating applies above 40 °C — the rated current drops from 32 A at 30 °C to 27.84 A at 50 °C (–). IP20 protection is standard for installed distribution boards with conductors connected; the enclosure is halogen-free and silicon-free.","metaTitle":"Siemens 5SU9356-7KM32 SENTRON RCBO, 32 A, 6 kA, Type A","metaDescription":"Siemens 5SU9356-7KM32 SENTRON RCBO, 32 A rated, 6 kA breaking capacity (EN 60898), Type A, 1P+N, C-curve.

The 5SU9356-7KM32 is a 32 A Type A C-curve device; the 5SU9354-7KK16 is a 16 A Type A C-curve device.
