The 45 mm width and 97 mm depth fit a standard 35 mm DIN rail (DIN EN 60715) with screw and snap-on fastening, so it drops into existing SIRIUS 3RV mounting rails without panel rework. ## Mounting and clearance — panel fit Mounting position is any, so vertical or horizontal orientation in the enclosure is fine. Clearance requirements: 50 mm upward, 50 mm downward, 30 mm at the side. Zero forward clearance needed, which helps when the panel door or a busbar shroud is close. The screw-type terminals on the main current circuit accept 2×(0.75–2.5 mm²) solid/stranded or 2×4 mm² — M3 screws for the main contacts. For a transformer-protection install, the 0.2 kW rating at 230 V and 1 hp at 460/480 V give a quick horsepower-to-kW cross-check for the protected transformer's secondary. The lifecycle stage is listed as current, meaning Siemens continues to manufacture the 3RV2411-0KA10 as an active catalog line. No last-time-buy or phase-out notice is on record.","metaTitle":"Siemens 3RV2411-0KA10 SIRIUS Circuit Breaker, 100 kA, Class","metaDescription":"Siemens 3RV2411-0KA10 SIRIUS circuit breaker for transformer protection. 100 kA breaking capacity at 400 V, Trip Class 10, 45 mm wide, DIN rail mount.
