It uses a 130 mm shaft to couple the breaker handle through an enclosure door, with an IP64 seal keeping washdown and dust out of the panel interior. This is the -0C variant — currently in phase-out, with the successor 3RV2926-1C carrying a different drilling pattern, so any panel cutout or door prep will need updating when you switch over. The 66 mm width and 66 mm height match the standard S00/S0/S2/S3 breaker face, so it sits flush on the door without extra clearance. The 50 mm depth is the mechanism body behind the panel — the 130 mm shaft length is what reaches from the door to the breaker, so verify your enclosure depth against that figure. Mounting position is any orientation, fixed via screw fixing, so it's straightforward to retrofit into an existing door cutout as long as the drilling pattern matches the -0C layout. The IP64 seal means it's fine for general industrial environments with dust and splash; not rated for hose-down or submersion. The 3RV2926-0C is flagged as product phase-out with a listed successor, 3RV2926-1C. The key difference is a drilling pattern change — the -1C won't drop into the same door cutout without modification. The operating frequency is rated at 15 operations per hour, which is typical for an emergency-stop mechanism — not a cycling actuator. The part carries a substance prohibitance date of 07/01/2006, indicating RoHS compliance from that date onward.","metaTitle":"Siemens 3RV2926-0C SIRIUS Door-Coupling Rotary Operator, EME","metaDescription":"Siemens 3RV2926-0C SIRIUS door-coupling rotary operating mechanism for EMERGENCY-OFF on S00-S3 breakers. 130 mm shaft, IP64.

The 3RV2011-0AA10 is a completely different product (a motor-protective circuit breaker, not an operator mechanism) and won't serve the same function. The only official replacement path is the 3RV2926-1C, with the drilling-pattern caveat."},{"question":"Will 3RV2926-0C drop into a panel specified around 3RV2011-0AA10?","answer":"No — the 3RV2011-0AA10 is a motor-protective circuit breaker (size S00), not a door-coupling operator. The 3RV2926-0C mounts on the enclosure door and couples to the breaker handle; it doesn't replace the breaker itself. If the panel already has a 3RV2011-0AA10 breaker, the 3RV2926-0C can be used as the door operator for that breaker, since it's compatible with S00 frames."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV2926-0C","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RV2926-0C when reusing this data.
