The 30 mA trip threshold covers personnel protection against direct contact in standard distribution boards. Mounts on DIN rail, 7 modular width units wide. Feed from top or bottom — no orientation restriction. The IP20 rating applies once the distribution board is installed and conductors are connected; that's standard for enclosed panel gear. Installation depth is 70 mm into the enclosure, overall depth 77 mm including the front face. Touch protection is built in. Rated current derates with ambient temperature: 25 A at 30 °C, 23.3 A at 40 °C, 22 A at 45 °C, 21.5 A at 50 °C, 20.8 A at 55 °C. Surge voltage resistance 4 kV. Operating frequency 50/60 Hz.","metaTitle":"Siemens 5SU9346-1CR25 SENTRON RCBO, 25A C-Curve 30mA 4P","metaDescription":"Siemens SENTRON 5SU9346-1CR25 RCBO, 25A rated, C-curve, 30mA residual current, 4-pole, 6kA breaking capacity.
