The Siemens 3RV2011-1CA10-ZW97 is a SIRIUS motor protection circuit breaker designed for motor protection in control panels. It snaps onto a 35 mm DIN rail per DIN EN 60715 and accepts screw-type terminals for the main current circuit. Trip class CLASS 10 means it clears a locked-rotor condition within 10 seconds at the rated current — standard for general-purpose induction motors driving pumps, fans, and conveyors. The breaker is rated for a maximum of 15 switching operations per hour in AC-3 duty (motor starting), so it's sized for infrequent starts, not jogging or reversing service. Short-circuit breaking capacity hits 100 kA at 400 V and 500 V, dropping to 10 kA at 690 V. That 100 kA figure at 400 V means it can be used on high-fault-capacity industrial networks without needing an upstream current-limiting fuse — a real panel-space saver where SCCR requirements are stiff.
Footprint and mounting
Dimensions are 97 mm deep, 45 mm wide, and 97 mm tall — a compact 45 mm width that fits standard motor-starter footprints. Fastening is screw and snap-on onto 35 mm DIN rail; mounting position is any, which simplifies layout in crowded enclosures. Clearance requirements: 50 mm upwards and downwards, 30 mm to the side, zero forwards or backwards.
