Its 0.8 A rated continuous current sets the motor full-load current it can handle continuously without tripping. 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.
