Re: industrial motor starters OT
Just to clear the size/type issue up, motor starters are rated by NEMA size, the enclosures are rated by type (see below). Unfortunately, what you have is for big motors such as used for plant air compressors, air makeup houses, big pumps and the like.
Some other problems are the brand, most people I deal with use Allen-Bradley. I expect the warranties are long expired so any reputable panel shop would not touch them. That $600 you quoted is the list price not the sale price. Everybody gets a discount multiplier, for moderate users I think it's in the neighborhood of 0.58 or 58% of list and includes delivery to their door.
A company I used to work for, and still do time to time, was in the automotive conveyor business. They had bunches of this stuff lying around in Allen-Bradley in the size 1 & 2. For inventory this stuff was valued at 5 to 10 cents on the dollar, about 5 years later they auctioned it off to employees. None of it sold for much and the rest was thrown in a dumpster.
You need to look for end users and be ready to take pennies on the dollar. You might try making a list and sending it to the Plant Engineer of any factories in the area and maybe the local water treatment plant. See if Gramps knows any end users in the area.
I'm sorry if I burst your bubble but you should know were you are bargaining from rather than pass up a realistic offer by thinking it's worth more than it is. I sincerely hope this is not Grandpa's 401k.

NEMA Type Enclosures
Type 1. General Purpose: For general purpose applications indoors and where atmospheric
conditions are normal, designed to prevent accidental contact with current carrying parts of the
equipment. A Type 1 enclosure serves as a protection against dust and light, undirected splashing,
but is not dust-tight.
Type 2. Drip Tight: Similar to general purpose type, with shields added to protect against
dripping. Construction as to exclude falling moisture or dirt. A Type 2 enclosure is suitable for
application where condensation may be severe such as is encountered in cooling rooms or laundries.
Type 3. Weather Resistant: For use where exposed to rain or sleet and on docks, canal locks
and in subways or tunnels.
Type 4. Watertight: For use outdoors or where equipment might be subjected to splashing,
dripping or hose directed stream of water. A Type 4 enclosure is suitable for application outdoors
on ship docks and in dairies, breweries, etc.
Type 5. Dust-Tight: Prevents entry of dusts into controllers used in such non-hazardous areas as
cement mills, steel mills and coke plants, where dust or lint would interfere with the operation of the
Type 6. Submersible: For use where the unit might be submerged in water, as in mines, quarries
Type 7. Hazardous Locations: For use in Class I, Groups A, B, C or D hazardous locations
containing gases. Divisions I and II are included.
Type 8. Hazardous Locations: Similar to Type 7 except that the contacts are immersed in oil.
Intended for use for hazardous gases are corrosive.
Type 9. Hazardous Dust-Tight: For use in Class II, Groups E, F or G hazardous locations such
as flour mills, grain elevators or textile mills.
Type 10. Bureau of Mines: For use in coal mines. This enclosure is designed to meet the
explosion-proof requirements of the U.S. Bureau of Mines. It is suitable for use in gaseous mines.
Type 12. Industrial Use: Enclosures designed for use in automotive and other industrial plants, to
protect equipment against dirt and oil by preventing seepage of infiltration and keeping lint fibers and
flyings out of the controller. This type of enclosure has found wide application as a substitute for
Type 1 enclosures and is mandatory in the JIC Electrical Standards for Industrial Equipment.
