The Siemens 3RV2711-0BD10 is a SIRIUS circuit breaker in size S00, designed for system protection per UL 489 and CSA C22.2 No. 5.
Rated operating voltage spans 20 to 690 V, covering low-voltage distribution and motor branch circuits. The 100 kA interrupting rating holds across 240 V, 400 V, 500 V, and 690 V AC — that's a flat SCCR curve, so you don't lose headroom at higher voltages. The -20 °C floor matters for unheated enclosures in cold climates; the +60 °C ceiling covers most industrial switchgear rooms without derating. Mechanical endurance is 100,000 operations typical on main contacts. Maximum switching rate is 15 operations per hour at AC-3 duty.
The 45 mm width (3 module spaces) and 97 mm depth fit standard enclosure backplates. Terminal capacity: 1 to 10 mm² solid or stranded, up to 2x 10 mm² — enough for the load-side conductors on a size S00 frame. Screw terminals on the main circuit, M4 thread for main contacts. Mounting position any, so vertical or horizontal rail orientation is fine. Clearance required: 70 mm upward and downward, 30 mm at the sides, 0 mm forward and backward — the zero forward clearance means it can sit flush against a panel door or busbar cover.
