The Square D LV426909 is a circuit breaker handle, classified under Circuit Breaker General Accessories. It's the part you grab to manually trip or reset the breaker — no electronics, no coil to burn out, just a mechanical interface that connects to the breaker mechanism inside the panel.
This is a handle, so the only real spec that governs fit is the breaker frame it mates to. Square D uses a handle-per-frame mapping — the LV426909 fits a specific QO or NQ breaker family. If you're swapping a broken handle on an existing panel, match the breaker's catalog number against the handle's compatibility list. No voltage or current rating to worry about; the handle doesn't carry power. The UPC 606481286003 is consistent across the production run, so a replacement ordered against that code will match what's on the nameplate. No revision letter to chase.
