It mounts to the panel door and couples to the rotary actuator of a circuit-breaker, letting you open the breaker from outside the enclosure without opening the door. The mechanism is rated for use with SIRIUS circuit-breakers in sizes S0, S2, and S3 — the three most common frame sizes for motor-protective and molded-case breakers up to about 100 A. The red/yellow actuator is the standard EMERGENCY STOP color scheme per IEC 60204-1, so it integrates directly into a safety circuit without needing a separate label or adapter. The mechanism includes an interlock feature that can lock the breaker in the OFF position, and the product design explicitly supports locking into the OFF position — useful for lockout/tagout (LOTO) procedures on the panel door. The 330 mm shaft length is the critical dimension: it determines the maximum panel depth the mechanism can reach from the door to the breaker face. If your enclosure depth from door to breaker mounting plane is less than 330 mm, the shaft can be cut to length; if it's deeper, you need a longer-shaft variant. The mechanism body itself is 66 mm wide by 66 mm high by 50 mm deep — a compact footprint that fits a standard 22.5 mm panel cutout diameter for the rotary handle. The IP64 rating means the mechanism is dust-tight and protected against splashing water from any direction. That's sufficient for most industrial control panels in dry or damp environments; it is not rated for hose-down or submersion (IP65/IP67 would be required for washdown zones). Operating frequency is rated at a maximum of 15 operations per hour. That's fine for an EMERGENCY STOP actuator — it's not a frequent-use switch. If you need a door interlock that cycles every few minutes, this is not the part; look at a selector switch or pushbutton instead. The evidence includes a substance prohibitance date of 05/01/2012, which aligns with RoHS compliance for the EU directive. No UL or CSA approval marks are listed in the evidence, but the SIRIUS family typically carries those certifications — verify the specific approval marking on the nameplate if your panel requires UL-listed components.","metaTitle":"Siemens 3RV6926-0L SIRIUS Door-Coupling Rotary Mechanism, EM","metaDescription":"Siemens SIRIUS 3RV6926-0L door-coupling rotary operating mechanism for circuit-breakers S0-S3.
