Manual Motor Starter, 600 VAC, Current Production
The GV3M25 is a Square D manual motor starter rated 600 VAC — the kind of part you spec into a motor branch circuit when you want thermal and magnetic protection in one package, no separate overload relay needed. It's listed as current-production, so this isn't a scavenger-hunt obsolete part; it's a line item you can still order against an RFQ.
