HAUNI, order code 3RV1926-2BB00-0AA4.","salesMarkdown":"The Siemens 3RV1926-2BB00-0AA4 is a door-coupling rotary mechanism designed for circuit-breaker size S0 in the SIRIUS 3RV19 family. It includes the HANDHABE gray display plate with black FA. HAUNI markings. This mechanism mounts between the panel door and the circuit-breaker operating head, allowing the breaker to be switched from outside the enclosure while maintaining the door closed — a standard arrangement for MCC and distribution panels where operator access to the breaker handle must be external. Sized specifically for S0 frame breakers — verify the cutout dimensions and handle shaft length against your enclosure door thickness before ordering. The gray display plate with black FA. HAUNI text is a specific aesthetic variant; if panel labeling standards require a different legend, confirm compatibility.","metaTitle":"Siemens 3RV1926-2BB00-0AA4 Door-Coupling Rotary Mechanism, S","metaDescription":"Siemens 3RV1926-2BB00-0AA4 door-coupling rotary mechanism for circuit-breaker size S0.
