The Siemens 3RV2711-1FD10 is a SIRIUS circuit breaker in frame size S00, designed specifically for system protection under UL 489 and CSA C22.2 No. 5. This means it's listed as a branch-circuit protective device for North American panels — not just a motor-protective breaker for IEC applications. The 100 kA interrupting rating at 400 V AC gives real SCCR headroom for high-fault installations; at 690 V AC it still clears 6 kA, so it handles mixed-voltage lineups without cascading upstream.
Selectivity & coordination
For a panel originally built around the 3RV2021-1FA15: the 3RV2711-1FD10 shares the S00 frame size and the same 45 mm width and 97 mm depth. The key difference is the UL 489 system-protection listing on this part versus the IEC motor-protective design of the 3RV2021-1FA15. If the existing panel requires a UL 489 listed branch-circuit device for compliance, the 3RV2711-1FD10 drops in without rewiring — same footprint, same terminal arrangement. For a pure IEC motor-starting application, the 3RV2021-1FA15 with its integrated overload function may be the better fit.
Integration & wiring
Terminal screws take a Pozidriv size 2 tip with a 5–6 mm shaft diameter. The M4 main-contact bolts are standard for S00 frame. Clearance: 70 mm upward, 70 mm downward, 30 mm to the side — no forward clearance needed.
