It has a red/yellow actuator, interlock, and lockable OFF position. Mounts via screw fixing in any position. The mechanism couples through the enclosure door to the S3 circuit-breaker behind it; the 78 mm depth is the mechanism body itself, not the total projection through the door. Operating frequency is rated at a maximum of 15 operations per hour, which suits occasional emergency-stop use or maintenance isolation rather than frequent switching duty. Temperature range during operation is -20 to +70 °C, storage -50 to +80 °C — fine for most indoor panel environments, including near presses or ovens where ambient heat is a factor.","metaTitle":"Siemens 3RV2946-2C SIRIUS Door-Coupling Rotary Operating Mec","metaDescription":"Siemens SIRIUS 3RV2946-2C door-coupling rotary operating mechanism for circuit breaker size S3.
