What this kit does
The LAD9128GV is a factory-assembled kit for building star-delta starters. It bundles the electrical and mechanical interlock, power connection set, and a time-delay contact block (LAD S2) into one order code — one line item instead of three separate part numbers for the panel builder. Designed for three TeSys D contactors in the LC1D09 through LC1D18 frame size, paired with a GV2 motor circuit breaker, line-mounted. The kit covers the interlocking and timing logic that a star-delta transition requires.
