What this part is and what it does
The Siemens 3RV2011-0KA15-ZW97 is a SIRIUS motor protection circuit breaker with Class 10 trip, phase failure detection, and screw terminals.
Mounting and integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. At 45 mm wide and 97 mm deep, it occupies a single modular slot — no extra panel space needed beyond the standard motor starter footprint. Screw-type terminals on the main current circuit accept 2× (0.5…1.5 mm²) solid or stranded, or 2× (0.75…2.5 mm²). Mounting position is any orientation, which simplifies layout in crowded enclosures.
Key ratings in context
Rated operational voltage spans 20…690 V AC. Short-circuit breaking capacity at 400 V is 100 kA — sufficient for most industrial panelboards with high fault current. The auxiliary contact ratings cover 24 V (1 A), 60 V (0.15 A), 120 V (0.5 A), and 230 V (0.5 A), giving flexibility for control circuit integration. Ambient operating temperature range is -20…+60 °C; storage and transport range is -50…+80 °C.
