The breaking capacity is 100 kA at 400 V AC and holds at 500 V and 690 V AC — that is a high short-circuit withstand for a 0.8 A device, meaning it can clear a fault on a high-capacity distribution panel without upstream fuse coordination issues. Any mounting position is allowed, so it can be oriented horizontally or vertically in the panel to suit wire routing. ## Environmental and mechanical tolerance Shock resistance is 25 g for 11 ms, which covers most industrial vibration environments. The auxiliary switch is present for remote status indication; no ground fault detection on this variant. For a BOM freeze or replacement planning, the 3RV1011-0GA10 and 3RV1011-0HA10 are smaller-frame siblings in the same SIRIUS family — same Class 10 trip, but different current ranges and breaking capacities. The 3RV6011-0CA10 is a different series with different mounting and ratings. The 3RV1021-0HA10-0FJ0 is the correct 0.8 A, 100 kA variant.","metaTitle":"Siemens 3RV1021-0HA10-0FJ0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0HA10-0FJ0 SIRIUS motor protection circuit breaker, 0.8 A continuous rating, 100 kA breaking capacity at 400 V, Class 10 trip, screw and snap-on DIN rail mount.
