Lessons from the past

Let me introduce you to a bit of history here. I currently work in the electronics repair field, where technology keeps going faster, better, and more complex. But once in a while, a veteran from long ago comes in for some R & R, and you just can't help but marvel at how things used to get done. Introducing just such a device, from General Electric Corp. (back when GE was the biggest kid on the block)

I have no idea who sent this in, or where it has been working, but it's a wonder of engineering for the day. Best I can tell, late 1940's to perhaps mid 1950's manufacture- bakelite and steel frame, hand wound coils, clockworks balanced and still working.

Oh, what does it do, you ask? Not much- it's a time-delayed breaker, sort of like the one in your home's distribution panel. Except this one has multiple taps to choose the current you want to trip out at- from 0.5 amps to 2 amps- and a hand-set time delay, from 0 seconds up to 7 seconds. Just enough time for the motor or light or whatever to get over inrush current and settle down before we go and set off the overcurrent alarm and shut things down.

Yeah, I got it fixed- problem was a broken bakelight terminal strip where someone had overtightened a screw. I made sure to do it right, too. This one deserved good treatment, after so much time on the job. I hope one day- a long time from now- when the old girl is finally retired, they have the decency to give her to the a museum or at least send her home with someone who cares. They don't make 'em like that any more.
