At 400 V — the most common industrial motor voltage — 50 kA covers nearly any installation with a transformer upstream. The 55 mm width and 140 mm height are standard for this SIRIUS frame size; depth is 149 mm, so account for that behind the panel door. Main circuit terminals are screw-type box terminals accepting 2x (0.75…16 mm²) solid or 2x (0.75…25 mm²) stranded, with a single terminal taking up to 35 mm² stranded. Auxiliary and control circuit terminals are also screw-type. Front face is IP20 — fine inside an enclosure, not for wet areas. ## Thermal management Total power dissipation in hot operating state is 29 W, or 9.7 W per pole. That's moderate for a 45 A breaker — enough to consider in a sealed, uncooled enclosure with multiple devices ganged together. Shock rated at 25g for 11 ms.","metaTitle":"Siemens 3RV1031-4GA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1031-4GA10-ZW96 SIRIUS motor protection circuit breaker. 45 A continuous, 22 kW at 400 V, Class 10 trip, 50 kA breaking capacity at 400 V.
