It's not a general-purpose distribution breaker; the electronic short-circuit trip is tuned for motor starting inrush, so you don't get nuisance trips on a 250 A AC-3 motor load at 400 V. Continuous current is 250 A, and the interrupting rating hits 120 kA at 400 V AC — that's a lot of fault current headroom for a motor branch. At 690 V it still holds 70 kA. The screw-type terminals on both main and auxiliary circuits mean you're wiring it with lugs, not bus bars; panel builders will appreciate the 105 mm width and 205 mm height, with screw fixing to the mounting plate. ## Sizing and selectivity notes The 250 A AC-3 rating at 400 V is the working number for motor duty — that's the current it'll carry continuously while switching a motor load. The 120 kA SCCR at 400 V means it can safely clear a fault up to that level without blowing apart or welding contacts, which is critical for coordination with downstream components. If you're feeding a panel with a transformer or generator that can deliver that kind of fault current, this breaker will hold the line.","metaTitle":"Siemens 3RV1363-7EN10 SIRIUS MCCB, 250 A, 120 kA @ 400 V","metaDescription":"Siemens 3RV1363-7EN10 SIRIUS molded-case circuit breaker, 250 A continuous, 120 kA breaking at 400 V AC.
