The Siemens 3RV2711-4AD10-0RT0 is a size S00 circuit breaker from the SIRIUS 3RV2 family, rated for 20... 690 V and delivering a 30 kA breaking capacity at 400 V AC. At 240 V AC it handles 100 kA, at 500 V AC 10 kA, and at 690 V AC 4 kA. Rated for motor duty at AC-3 up to 690 V, with a maximum of 15 operating cycles per hour. The main contacts are rated for 100 000 typical mechanical operations. Power loss in hot operating state is 9.25 W at AC.
Mounting and clearance — panel fit check
Dimensions are 45 mm wide, 144 mm high, 97 mm deep. Clearance requirements: 70 mm upwards, 70 mm downwards, 30 mm at the side, 0 mm forwards and backwards. That zero forward clearance means no extra deadfront space needed — the breaker can sit flush against a panel door or cover. Main contact screws are M4; use a Pozidriv size 2 tip with a 5 to 6 mm diameter shaft.
Fuse coordination and operating conditions
Back-up fuse ratings are specified per voltage: gG 80 A at 240 V, gG 63 A at 400 V, gG 50 A at 500 V, gG 40 A at 690 V. This governs the upstream fuse size for selective coordination — match the voltage to your line-to-line supply. No ground fault or phase failure detection built in — that's a separate add-on module if your application requires it.
