It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, which means it drops into any standard industrial panel without extra bracketry; clearance distances are 50 mm upwards, 50 mm downwards, 10 mm at the side, and 0 mm forwards and backwards, so plan for those gaps around the breaker for heat dissipation and arc flash containment. The operating temperature range is -20 to +60 °C, and storage/transport range is -50 to +80 °C, so it handles the ambient heat near a rolling mill or furnace area without derating, as long as the enclosure ventilation keeps internal air below the 60 °C ceiling. Main circuit terminals accept screw-type connections for 2×(1…35 mm²) or 1×(1…50 mm²) solid or stranded copper, sized for motor branch circuits up to 52 A at 480 V and 600 V. ## Electrical Ratings Breaking capacity varies by voltage: 100 kA at 240 V, 30 kA at 400 V, 4 kA at 500 V, and 2 kA at 690 V — the 30 kA at 400 V is the figure most panel builders and site engineers will use for coordination in 400 V industrial networks. Rated operational voltage spans 20…690 V, and the motor ratings at common utilization voltages are 10 hp at 230 V, 15 hp at 200/208 V, and 20 hp at 220/230 V — these are the AC-3 motor switching ratings for three-phase induction motors. Switching frequency at AC-3 maximum is 15 operations per hour, which is typical for motor starting duty — not suitable for high-cycling applications like rapid reversing or jogging without oversizing. ## Dimensions and Clearances Dimensions are 149 mm depth, 55 mm width, and 140 mm height — the 55 mm width occupies three 18 mm DIN modules, so it fits in a standard 600 mm wide enclosure with room for adjacent breakers and contactors. Required clearances: 50 mm above and below, 10 mm to the side, and 0 mm in front and behind — the zero forward clearance means it can be mounted flush against a panel backplate or busbar support without additional spacing.","metaTitle":"Siemens 3RV2031-4WA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2031-4WA10-ZW96 motor protection circuit breaker, CLASS 10 trip, 30 kA breaking capacity at 400 V.
