It sits in the 01048-LE 250, 400_FRAME category — that frame size tells you the physical footprint and the interrupting capacity class it belongs to. For a panel builder or MRO planner, this means it fits the standard cutout and bus bar spacing for that frame family, so you're not re-drilling the backplate.
Lifecycle and sourcing — active, no LTB clock
Lifecycle stage is marked current and product status is Active. That means no last-time-buy notice, no phase-out schedule. For a shutdown planner or category sourcing lead, this part is on the critical path only by your own lead-time window — not because the manufacturer is pulling it.
600V is the maximum line-to-line voltage the breaker can interrupt — common for 480V and 600V industrial services. 150A is the continuous current rating at 40°C ambient; if your panel ambient runs higher, expect a derate per the manufacturer's thermal curve. The 01048-LE 250, 400_FRAME category also implies the interrupting rating (typically 25 kA or 65 kA at 480V depending on the specific variant), though that figure isn't listed here — verify against your available fault current before committing the BOM line.
