What this part is and where it fits
The ABB 1SDA076415R1 is a lever lucid plate for the XT1 molded-case circuit breaker (MCCB) family. It is the transparent lever cover that sits over the breaker's operating handle, providing a clear window to view the handle position — ON, OFF, or tripped — while protecting the mechanism from dust or accidental contact. This is a panel-mount accessory; it snaps onto the XT1 breaker front after the breaker is installed on the DIN rail or mounting plate.
