The Siemens SIRIUS 3RV1041-4JA15-ZX95 is a motor protection circuit breaker rated for 63 A continuous current and 30 kW at 400 V in AC-3 duty. Breaking capacity is 50 kA at 400 V AC, 100 kA at 240 V, tapering to 6 kA at 690 V.
Main circuit terminals accept solid conductors: 2× (0.5–1.5 mm²) and 2× (0.75–2.5 mm²). Stranded conductors on the main circuit: 2× (10–50 mm²) or 1× (10–70 mm²). The auxiliary switch terminals are screw-type, rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. The auxiliary switch is a transverse design and is a product extension — it ships with the breaker, not as a separate add-on.
Shock resistance is 25 g for 11 ms. Mounting position is any orientation. Dimensions: 70 mm wide, 165 mm high, 174 mm deep. The depth of 174 mm is the full body depth including the terminals — ensure at least that much clearance behind the panel door or enclosure cover. Backwards and side clearances are 0 mm, so the breaker can be mounted flush against adjacent devices or the panel wall without derating.
