The Siemens 5SV3346-6GV01 is a 4-pole residual current circuit breaker (RCCB) from the SENTRON 5SV3 series, rated 63 A at 400 V AC. It detects Type A fault currents — sinusoidal AC and pulsating DC — making it suitable for circuits with rectifiers, switched-mode power supplies, or single-phase drives that produce pulsating DC leakage.
Rated IP20 with the distribution board closed and conductors connected — it's a panel-internal device, not for wet or outdoor locations.
Rated 63 A continuous from 40 °C up to 60 °C (–). Above 60 °C the current must be derated: 57.35 A at 65 °C, 48.84 A at 70 °C. Mounting position is unrestricted.
