Yes this ballast is rated for 34W and 40w tubes. These are the best rapid start ballasts made IMO. I love Universal ballasts, especially the Therm-O-Matic ones with PCBs-loaded capacitors.

Nice! Interesting that it isn't thermally protected but it was made after 1980.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

Hmm that is interesting. At first I just assumed they dropped the Therm-O-Matic name by then but I think it should say thermally protected somewhere on the label.

It should have a -tc-p suffix in the model number if it is thermally protected.

these must've been sold for replacement purposes only, still a really cool find even if not thermally protected

Weird how its not thermally protected? I wonder if it wasn't a issue anyway with the design able to handle f34 lamps

T12/ t17 there's a reason they made heavy magnetic ballasts

Kinda interesting that they were made late enough to list F34 lamps but not have thermal protection. Anyway, the ballasts seem to be packaged for replacement use so maybe they offered replacement ballasts without thermal protection for some niche application.

I wonder why they would make a ballast with no protection, even for use as a replacement. That's like an electrician replacing a standard duplex receptacle in a bathroom (on a non-GFCI protected circuit) with another duplex receptacle. Sure, that's what was there before but at the time it was originally installed that was acceptable. You can keep your old receptacle without GFCI protection as long as you want, but when it comes time to replace it, you must use a GFCI receptacle. I wonder why the same wasn't true for ballasts. I feel like someone could easily install this to replace a ballast that HAD thermal protection. Only explanation I can think of is what Joe mentioned, it's for some niche application.
