It trips on AC fault currents at a rated residual current of 100 mA, instantaneous — no short-time delay. Mounts on DIN rail (REG), occupies 4 width units (72 mm), and accepts conductors from 0.75 to 35 mm² solid or stranded. Rated 63 A continuous at ambient temperatures up to 60 °C. Above that, derating applies: 57.35 A at 65 °C, 48.84 A at 70 °C. Mounting position is unrestricted.","metaTitle":"Siemens 5SV4446-0LA SENTRON RCCB, 4P, 63A, 100mA, AC Type","metaDescription":"Siemens 5SV4446-0LA SENTRON 4-pole RCCB, 63 A rated, 100 mA residual, AC type, 10 kA SCCR.
