The Siemens 3RV1611-0BD15-ZX95 is a SIRIUS circuit breaker in size S00, designed specifically for fuse monitoring rather than motor protection. It carries a rated operational current of 0.2 A at 400 V in AC-3 duty (switching motor loads up to that current), with a voltage range of 20...690 V. The unit includes a transverse auxiliary switch with 1 NO + 1 NC contact, and uses screw terminals for the main circuit.
The 20...690 V rated range covers most low-voltage industrial systems up to 690 V line-to-line. The 20 mm upwards and 9 mm side clearance requirements match the standard S00 footprint, so it fits the same DIN-rail spacing as the motor-protection siblings in the SIRIUS family.
Panel integration
The screw terminals accept 2x (0.5...1.5 mm²) solid or stranded, or 2x (0.75...2.5 mm²) with ferrules.
