Molded Case Breaker, Testing, Repair?

[Joethemechanic]

I've got a ton of these 3 phase molded case breakers that came from a large plant's storeroom that I bought the contents of at auction some years back. So I have no history on them. I made my money back by like tenfold and still have some stuff left, so I don't really have anything into them.

So if I wanted to use them, how can they be tested? Are there any reputable companies doing testing and repair? Is it even worth having it done or are they paperweights?

Might be door stops if the draft isn’t too strong.

If you could identify what type and frame they are might help in determining usefulness or value.

Call quotes repair and test, see where it going, cost benefit analyze

I guess if I made my own enclosure that would be bad too. . Shame because most commercial electrical enclosures are expensive and not very well built. If I built one it would be a bit oversized and be made out of 8 gauge carbon steel

With or without SCCR marking?

There is no industry wide accepted procedure for drilling out rivets oe breaking apart glued components in order to repair or reconditioned molded case circuit breakers. You are at the mercy of any shop that offers this type of service. Evrnthpugh some companies offer this service they are usually scavenging parts from several breakers in order to come up with an untestable single device (AIC testing is destructive).
