The Siemens 3RV2711-1BD10 is a SIRIUS circuit breaker, size S00, designed for system protection according to UL 489 and CSA C22.2 No. 5. That means it's built to serve as a branch-circuit protective device in North American panels — not just a motor-protective overload relay, but a listed breaker that clears faults upstream of the load.
At 400 V AC this breaker is rated 100 kA interrupting capacity. That's the same at 240 V AC and 500 V AC — 100 kA each — so it handles high-available-fault panels without cascading upstream. The breaker also lists backup fuse requirements: gG 25 A at 400 V and 500 V, gG 20 A at 690 V. If you're coordinating with upstream fuses, those are the maximum ratings for the backup protection to hold the breaker's SCCR.
The screwdriver shaft diameter is 5 to 6 mm, Pozidriv size 2. Main contact terminals use M4 screws.
