No ground fault detection on this variant. Zero clearance needed at the sides or rear, so it packs tight in a panel — width is 55 mm, height 140 mm, depth 149 mm. Screw terminals on the main circuit accept 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. Substance prohibitance date of 07/01/2006 aligns with RoHS compliance. The part carries no REACH or UL listing in the available record, but standard Siemens SIRIUS motor-protection breakers are typically UL/CSA recognized; verify with the factory certificate for your jurisdiction. Compared to the 3RV6021-4DA10 (a SIRIUS Innovation series breaker), the 3RV1031-4AB10 uses screw terminals rather than spring-cage, and lacks ground-fault detection. The 3RV6021 also carries a higher 100 kA at 400 V rating. For a direct drop-in without rewiring, the 3RV1031-4AB10 shares the same 55 mm width and DIN-rail footprint, but terminal type differs — screw vs. spring-cage — so verify lug compatibility before substituting.","metaTitle":"Siemens 3RV1031-4AB10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4AB10 SIRIUS motor protection circuit breaker, 16 A continuous, CLASS 20 trip, 50 kA at 400 V.
