No ground-fault detection on this unit; that is handled separately downstream if required. Breaking capacity is 50 kA at 400 V AC, 100 kA at 240 V, dropping to 10 kA at 500 V and 4 kA at 690 V. At 400 V — the most common industrial supply — this breaker can interrupt a 50 kA prospective fault current without upstream fusing, which covers most panelboard and motor control center applications. Any mounting position is permitted. Dimensions: 55 mm wide, 140 mm high, 149 mm deep — fits a standard 55 mm module slot. Zero clearance required at the sides or rear, so breakers can be ganged without spacing. Main circuit terminals accept solid conductors 2x (0.75…16 mm²) or stranded 2x (0.75…25 mm²) and up to 1x 35 mm². AWG equivalents: 2x (18…2). Control circuit terminals are screw-type as well. Shock resistance rated at 25 g for 11 ms. IP20 protection on the front — suitable for enclosed panels where the front is operator-accessible but not washdown-rated.","metaTitle":"Siemens 3RV1031-4EB10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4EB10 SIRIUS motor protection circuit breaker, 32 A continuous, Class 20 trip, 50 kA at 400 V.
