Derate to 47.5 A at 40 °C, 46.5 A at 45 °C, 45 A at 50 °C, and 43.5 A at 55 °C — important when the breaker sits in a crowded enclosure with other heat sources. Depth is 77 mm (70 mm installation depth), height 90 mm. IP20 rating applies when installed in a distribution board with conductors connected. Touch protection is built in. Halogen-free and silicon-free construction suits environments sensitive to outgassing — clean rooms, medical facilities, or telecom shelters.","metaTitle":"Siemens 5SU9356-1KN50 SENTRON RCBO, 50 A, 30 mA, C-curve","metaDescription":"Siemens 5SU9356-1KN50 SENTRON RCBO, 2-pole, 50 A rated, 30 mA Type AC RCD, C-curve, 10 kA IEC 60947-2.
