The LE36350LI is a molded case circuit breaker rated 600V and 350A, classified under category 01048-LE 250, 400_FRAME. That 350A continuous rating means it handles the full load current of a large motor or a feeder circuit without nuisance tripping — sized for a 300–350A branch in a distribution panel or motor control center.
That means this breaker is still in regular production — no end-of-life notice, no last-time-buy clock running.
Packaged as a single unit. The 01048-LE 250, 400_FRAME category places it in the LE frame family — that's the physical envelope and mounting footprint you need to match when swapping into an existing panel or ordering a replacement for a failed breaker. Verify the frame size against your existing bus connections and enclosure cutout before committing.
