It ships with a 330 mm shaft, allowing the rotary handle to be mounted on the enclosure door while the breaker sits inside the panel. The front-side actuator is red on a yellow background — the standard EMERGENCY STOP color scheme per IEC 60947-5-5 — and carries an IP64 protection rating on the front face, meaning the door-mounted handle is sealed against dust ingress and splashing water. The mechanism itself is rated for up to 151 operating cycles per hour. Mounting is by screw fixing in any position. The mechanism occupies a 66 mm × 66 mm footprint on the door and requires 50 mm of depth behind the panel.","metaTitle":"Siemens 3RV1926-0L SIRIUS door-coupling rotary mechanism, 33","metaDescription":"Siemens 3RV1926-0L SIRIUS door-coupling rotary operating mechanism for S0-S3 breakers.
