The red/yellow actuator provides clear visual indication of the emergency-stop state, meeting the requirements for a panel-mounted emergency-off device that couples through the enclosure door. Rated for circuit-breakers size S2 — this mechanism mates specifically to the S2 frame of Siemens 3RV2 breakers. The 75 mm width and 75 mm height define the door cutout and the panel footprint; the 78 mm depth is the projection behind the door. Screw fixing means standard panel hardware, no special tooling. Mounts in any position, which simplifies layout in tight enclosures. The operating frequency of 151 operations per hour is the mechanical limit — fine for manual emergency-off duty, not for high-cycle machine interlocking. ## Environmental range Rated for operation from -20 to +70 °C and storage from -50 to +80 °C. The storage range exceeds the operating range — that limit governs handling and transport, not running conditions.","metaTitle":"Siemens 3RV2936-2C SIRIUS Door-Coupling Rotary Operating Mec","metaDescription":"Siemens 3RV2936-2C SIRIUS door-coupling rotary operating mechanism for S2 circuit breakers.
