The Siemens SENTRON 5SV4312-0GV01 is a 2-pole residual current circuit breaker (RCCB) rated for 25 A continuous and 30 mA trip sensitivity, AC residual current type. It's built for 230 V AC, 50 Hz systems and carries a 10 kA short-circuit current rating per IEC 61008-1, so it can handle fault currents up to that level without welding contacts or cascading upstream.
Mounting & Panel Fit
Snaps onto DIN rail (REG profile), 36 mm wide — that's 2 modular width units. The IP20 rating applies once the distribution board is closed and conductors are connected.
