The Trip Class 10 characteristic means it will trip within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a stall or locked-rotor condition. ## Breaking capacity and fault handling At 240 V AC it also delivers 50 kA; at 690 V AC the rating drops to 2 kA, so verify the available fault current at the point of installation if running at higher voltages. Ground fault detection is not included, so a separate ground-fault relay or RCD is needed if that protection is required. ## Dimensions and wiring The unit measures 149 mm deep by 55 mm wide by 140 mm tall. The 55 mm width is a standard 3-module footprint on a DIN rail, so it occupies three 18 mm slots. Main circuit terminals accept screw-type connections — 2×(0.5 to 1.5 mm²) or 2×(0.75 to 2.5 mm²) solid or stranded. The main contact terminal size is M6. Auxiliary contact ratings: 1 A at 24 V, 0.15 A at 60 V, 0.5 A at 230 V. The auxiliary contacts are rated for 0 A at 110 V, 125 V, and 220 V — meaning they are not intended for use at those voltages.","metaTitle":"Siemens 3RV2031-4EA15-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2031-4EA15-0BA0 SIRIUS motor protection circuit breaker, Class 10, 7.5 kW at 230 V, 50 kA breaking capacity at 400 V AC.
