For a panel fed by a transformer with a 50 kA prospective short-circuit current at 400 V, this breaker alone handles the fault — no series fuse coordination needed. The main circuit uses screw-type box terminals; stranded wire from 0.75 to 35 mm² single or 2× 25 mm² fits. Auxiliary and control circuit terminals accept solid 0.5 to 2.5 mm² or stranded 0.75 to 2.5 mm². Zero clearance at the sides and rear means no extra air gap between adjacent breakers — the 55 mm width per pole is the only space consumed. IP20 on the front protects against finger contact; the interior of the panel must provide the rest of the enclosure rating.","metaTitle":"Siemens 3RV1031-4BA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4BA15 SIRIUS motor protection circuit breaker, 20 A continuous, 7.5 kW at 400 V, Class 10 trip, 50 kA breaking at 400 V.
