What it is and what it fits
The LAD9744 is a terminal cover for the load side of a TeSys Deca contactor, rated for 40 A. It's an installation accessory — a plastic shroud that goes over the load-side power terminals to provide finger-safe protection and maintain clearance. It fits the TeSys Deca contactor range, so it's compatible with contactors like the LC1D40 series.
