The LE36225LSG is a molded case circuit breaker rated 600V and 225A, catalogued under category 01048-LE 250, 400_FRAME. This is the breaker you spec when the panel schedule calls for a 225A frame with 600V class insulation — common on feeder circuits in industrial distribution panels where you need overcurrent protection on a motor control center or a lighting panel tap.
That means this order code is still in the manufacturer's active catalog — no end-of-life notice, no last-time-buy window to watch. For a BOM line that needs a 225A MCCB with a 600V rating, this part is a straightforward fit.
