The Siemens 3RV1611-0BD10 is a SIRIUS circuit breaker in frame size S00, designed specifically for fuse monitoring — it detects a blown upstream fuse and signals that condition rather than serving as the primary overcurrent protective device. Rated operational voltage spans 20 to 690 V, and the interrupting capacity holds at 100 kA across the common industrial voltages: 240 V, 400 V, 500 V, and 690 V AC.
Dimensions are 45 mm wide, 90 mm high, 75 mm deep — the S00 frame width matches the standard 45 mm modular spacing, so it occupies one slot on a DIN-rail panel. Clearance requirements: 20 mm above and below, 9 mm to the side, zero forward or backward — tight enough for dense panel layouts.
Main circuit connections use screw-type terminals accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded copper — M3 thread on the main contacts.
