Accepts solid or stranded copper: 2x (1…2.5 mm²) or 2x (2.5…6 mm²) per clamp. Zero overhang backwards or at the side — sits flush on the rail, which keeps the gland plate layout predictable. ## Protection and ratings Rated for 690 V max (AC-3), 6 kV surge withstand. Operating frequency tops at 15 operations per hour at AC-3. Shock rated 25g / 11 ms. IP20 on the front — fine inside a closed panel, not for washdown zones. Storage temp -50 to +80 °C; operating -20 to +60 °C.","metaTitle":"Siemens 3RV1021-0FA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0FA10 SIRIUS motor protection circuit breaker, 0.5 A continuous rating, Trip Class 10, 100 kA breaking capacity at 400 V AC.
