The 3RV1936-2BB00-0AA4: This mechanism mounts to the enclosure door and couples to the rotary operator shaft of the 3RV circuit breaker or 3RT contactor mounted on the DIN rail inside. The special inscription is applied to the front bezel or handle — verify that the FA. HAUNI marking matches what your panel builder expects on the nameplate or the as-built drawing. The mechanism itself does not carry any electrical rating; it is purely mechanical, so no derating or SCCR coordination applies.
