| Design Of The Product | For motor protection |
Rated operating voltage spans 20 to 690 V, covering most low-voltage motor circuits globally. The 176 mm depth fits standard 200 mm deep enclosures — no need for a deeper gland plate. Screw terminals accept solid or stranded conductors: 2×(2.5…16 mm²) for the main circuit and 2×(2.5…50 mm²) or 1×(10…70 mm²) for line/load connections.
It is rated 30 kA at 400 V, which means it can safely interrupt a fault current up to 30,000 A at that voltage without upstream protection needing to clear.
Both are SIRIUS motor protection breakers with the same DIN rail footprint and screw-terminal style, but the 3RV2041-4JA15 is rated for higher current (63 A at 480 V vs the 3RV2021-4NA25's lower rating). Verify the load current and breaking capacity before substitution — the physical fit is the same, but the electrical rating must match the application.
