Breaker Refurbishment
Breaker Refurbishment
(OP)
I am very new to my position which is power system reliability and maintenance engineer at a Tire MFG plant. I inherited this job and a circuit breaker refurbishment project. The project consists of sending out Westinghouse DS-206, electrically operated, circuit breakers out for complete refurbishment and having a new trip kit installed. Typically we send the trip overload unit to the vendor because of a contract we have with the trip kit supplier. Since I am involved now, I have seen some of the cost to do a refurbishment on just one of these breakers. I thought the price was very expensive considering the breaker is smaller than a car engine. My question is, does anyone have an idea of average costs to have these breakers refurbished? Or is the vendor taking us for a ride. What medium voltage breakers?
Thank's,
Steve W.

I'm not sure the size comparison to a car engine has much relevance. A pacemaker is pretty small, but costs many times what a car engine costs. That's not something I'd want to cut corners on either.

Our shop does all of this stuff, we put 40-60 man hours into a DS-206. Other shops may just clean it up, scotch brite the contacts, put some spray lube in the mech, slap on the trip unit and send it out, they will put about 8 man hours into this breaker. Your price all depends on what you require to be done. You can check with PEARL and download thier specs for reconditioning and remanufactureing breakers. www.pearl.org
P.S. MVCB's have voltage ratings from 5kV-69kV and can be air, gas, vacuum, or oil type.

But a remanufacture requires the contacts to be replated, not just thrown in a polishing machine. Now a recondition (Again, per PERAL specs)in 8-16 hours is about right and I think that is what you are describing.

Check that link for PEARL. Goes to some computer-related site. Assume www.pearl1.org was the intended link?

If we learn from our mistakes I'm getting a great education!
