The LE36200LS is a molded case circuit breaker rated 600V and 200A, falling under Category 01048-LE 250, 400_FRAME.
The 200A continuous rating at 600V tells you this breaker is sized for a main feeder or a large branch circuit in a 600V-class distribution panel — common in North American industrial plants running 480V or 600V delta systems. The 01048-LE 250, 400_FRAME category indicates the physical frame size and mounting footprint; if you are replacing an existing LE-series breaker in the same frame, the bolt pattern and bus connection should match. Single-unit packaging (1 per package) means you order each breaker individually, not in a multi-pack.
