What am I looking at?

I don't believe they have enough beef to be (high voltage) protection MOV's but they are more than likely for voltage suppression(spikes) of some kind in the form of MOV's.Its hard to see just how they are wired but a series/parallel network of some kind.
I'm just guessing,,,,,,,,,,,,,,,,,a curious need to know exists tho:)

A SS timer in the upper left along with the single pole relay, switch off the start capacitors. Hmm. Start/run capacitors. It is not wired correctly. There should be a connection to the Blue wires from the terminal block.

Tell us where the cable in the lower right goes/comes from.
 
I went and looked up an image of a phase converter and I believe hillbilly1 & ActionDave nailed it.I'd even bet on it :thumbsup:

What I do see for sure is that the neutral and the grounding conductors are both bonded to the cabinet, a definite no-no.

Red connects to blue through a set of capacitors
Black connects to blue through a set of capactitors
Black connects to yellow through a set of capacitors
Yellow connects to blue if the relay is closed
The relay coil is fed by red and black through a block which is a solid state something.
There are two extra knockouts in the bottom of the 3R cabinet.

Supposition -- this a phase assist with the input wired and the output not wired.
Supposition -- it was not wired by an electrician who understands the different between and neutral and grounding.

Nobody knows where the other end of white and bare are connected. Maybe the electrician was doubling down on bonding but did not have any green tape.

OK, I'll change my assessment:

Wired by an electrician who doesn't understand either:
1) color codes are important
2) the bare grounding conductor in the cable is properly sized for the hot wires in the cable.

Either way if I were inspecting it, it would fail.
 
It's actually more than just a static phase converter. It is a balanced phase converter. The brown caps to the right are the start caps, and the silver are the balancing run caps. The small block in the upper left is most likely a voltage controlled relay that disables the start caps when the generated voltage reaches the set threshold.

There is no reason for the neutral to even be in the cabinet, so it should have just been capped off. It's fairly neat, except for having the caps glued to the enclosure wall. If the glue were to let loose, there could be a short to the chassis.

It has some value on eBay, but it would be better to know what the original motor size was.
 
I was with you Cowboy...looked like a flux capacitor to me.....I've been out of the field too long:huh:
