The Siemens 3RV2711-0DD10 is a SIRIUS circuit breaker in size S00, designed for system protection per UL 489 and CSA C22.2 No. 5. Mechanical life on the main contacts is typically 100 000 operations. The breaker is rated for AC-3 switching up to 690 V at a maximum of 15 operations per hour, which suits motor-circuit protection in conveyor zones or pump panels where the load cycles several times a shift.
Mounting position is any orientation. Clearance requirements: 70 mm above and below, 30 mm to the side, zero forward or backward. Main contact screws are M4; use a Pozidriv size 2 tip or a 5–6 mm diameter screwdriver shaft.
