Breaking capacity runs 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC — so on a 400 V line you've got plenty of headroom for high-fault panels. Front IP20 keeps fingers out of the live terminals. A slower class (e.g. Class 20) would let the motor cook longer; a faster one (Class 5) might nuisance-trip on start-up inrush. The 45 A continuous rating and 22 kW at 400 V match up with a 45–50 A motor full-load current on a 400 V supply. If your motor nameplate says 48 A FLA, this breaker is sized right. If you're filling a BOM line or replacing a failed unit on a live panel, this is the current-production direct fit. Zero clearance needed at the back or sides for heat dissipation. Terminals accept 2x (0.75–16 mm²) solid or 2x (0.75–25 mm²) stranded, plus a single up to 35 mm² stranded. That covers most motor circuit feeds up to around 10 mm² per phase; for larger conductors you'd step up to the next frame size. Finger-safe touch protection (IP20 front) means the panel builder doesn't need additional covers over the terminals for basic shock protection.","metaTitle":"Siemens 3RV1031-4GA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4GA10 SIRIUS motor protection circuit breaker, 45 A continuous, Class 10 trip, 50 kA at 400 V AC.
