The 30 mA trip threshold covers personnel protection against direct contact; Type A means it catches pulsating DC residual currents from rectified loads like VFDs or LED drivers, not just sinusoidal AC. ## Integration Notes Touch-protected terminals (IP20 with connected conductors in an installed distribution board) meet finger-probe safety. ## Thermal Derating & Environment Derate linearly: 23.5 A at 40 °C, 22.75 A at 45 °C, 21.75 A at 50 °C, 20.25 A at 55 °C. Operating range -40 to 75 °C covers unheated enclosures and high-temp machine cabinets. Halogen-free and silicon-free construction suits clean-room or sensitive electronics environments where outgassing must be minimized.","metaTitle":"Siemens 5SU9356-7KK25 SENTRON RCBO, 2-pole 25A Type A 30mA C","metaDescription":"Siemens SENTRON 5SU9356-7KK25 RCBO, 2-pole, 25 A rated, Type A, 30 mA residual, C characteristic, 6 kA breaking capacity.
