The SIRIUS 3RV1041-4JA10-0DA0 is a system circuit breaker in size S3, designed for system protection — not motor protection — with an A-release adjustable from 45 to 63 A and a fixed short-circuit release of 819 A.
Screw terminals for the main circuit — torque to the specified range on the nameplate. No auxiliary switch or removable terminal for the control circuit on this variant, so any status feedback requires an external auxiliary contact block. The 100 kA SCCR means the panel designer must verify that downstream components are rated for the let-through energy at that fault level.
What it doesn't do
No ground fault detection, no phase failure detection. This is a straight thermal-magnetic system protector — it trips on overload via the thermal A-release and on short-circuit via the magnetic trip set at 819 A. If your circuit needs phase-loss or ground-fault sensing, you'll need a separate relay or a different breaker variant.
