It carries a continuous rated current of 0.2 A and a Trip Class 10, meaning it will trip within 10 seconds at 7.2× the thermal setting — standard for protecting general-purpose induction motors against locked-rotor conditions. Rated breaking capacity hits 100 kA at 400 V AC, so it can safely clear a bolted fault on a high-capacity distribution bus without upstream fuses needing to intervene. Phase failure detection is built in, catching a lost leg before the motor single-phases to failure. Snap-on mounting to 35 mm DIN rail per EN 50022, screw terminals for main and auxiliary circuits. The 45 mm width fits standard panel slotting; any mounting position is allowed. ## Sourcing & Lifecycle RoHS compliance date marked 01.05.2012. Finger-safe touch protection and IP20 on the front face meet standard panel safety requirements. ## Integration Notes Mounts on 35 mm DIN rail per EN 50022; screw terminals accept solid or stranded conductors up to 6 mm². The auxiliary switch slot is available for adding a remote status contact. Depth of 96 mm leaves clearance for standard enclosure depths. Ambient operating range -20 to +60 °C covers most indoor panel environments.","metaTitle":"Siemens 3RV1021-0BA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-0BA10 SIRIUS motor protection circuit breaker, 0.2 A rated current, Trip Class 10, 100 kA breaking capacity at 400 V.
