It provides a mechanical interface between the panel door and the breaker's rotary handle, allowing the operator to open or close the circuit breaker from outside the enclosure. The red/yellow actuator color signals its safety function per standard practice. ## Lifecycle and replacement This part is in product phase-out. The successor is the 3RV2926-3C, and the drilling pattern changes between the two versions, so a panel cutout modification will be required when migrating. Designed for circuit-breakers of size S0, the mechanism mounts via screw fixing in any orientation. The 75 mm width and 75 mm height fit standard panel cutout patterns for S0 accessories. The 78 mm depth accounts for the mechanism body behind the door; the 300 mm length covers the operating shaft and coupling hardware. The maximum operating frequency of 151/h sets the mechanical cycling limit for applications like frequent emergency stop testing. ## Environmental range The wide storage range covers unpowered transport and warehouse conditions; the operating range suits most indoor industrial panel environments without derating.","metaTitle":"Siemens 3RV2926-2C SIRIUS Door-Coupling Rotary Operating Mec","metaDescription":"Siemens 3RV2926-2C SIRIUS door-coupling rotary operating mechanism for S0 circuit-breakers.
