Ground fault detection is not included, so if that's required, an external ground-fault module or GFCI breaker must be added upstream. ## Mounting and wiring — DIN rail, screw terminals, IP20 front The 45 mm width (3 module spaces) fits standard enclosure grid layouts; depth is 81 mm, height 90 mm. Screw-type terminals on both main and auxiliary/control circuits accept solid or stranded conductors: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²) per clamp, or AWG 18…14 for the main contacts. Stripping and torquing follow standard Siemens SIRIUS practice — no special tooling needed. ## Lifecycle and sourcing — active, quoted to order RoHS compliance is documented with a substance prohibition date of 01/01/2013. The part carries CE marking as standard for the SIRIUS family; UL/CSA listings are typical for this series but should be verified against the specific variant's certification markings on the nameplate.","metaTitle":"Siemens SIRIUS 3RV1011-1KA15-0BA0 Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-1KA15-0BA0 motor protection circuit breaker, 12 A continuous, CLASS 10 trip, 5.5 kW at 400 V.
