GE Power Break Circuit Breaker

GE Power Break circuit breakers have long been a reliable product for GE.  After 30 years of production the Power Break 1 circuit breakers have been discontinued and obsoleted from the product line.

If you have a switchboard or application with these breakers there is no need to panic. Quality Switchgear has a huge inventory of frames and parts to keep you going for a few more years.

One of the problems with this long life is that the products go through several revisions and modifications that make them incompatible depending on the switchgear you own.

To help you find out what vintage you have and locate the accessories you may need the folks at Quality Switchgear  to help walk you through the solution. Use this video to help answer some questions:

Ok, its not electric exactly, but  I really love this music !! Might have to make them the honorary Quality Switchgear band, see what you think. We can always talk circuit breakers, but you can't always find good music:

Give it a listen : "Little Sad Eyes" and "Dark Don't Hide It"   this is Americana greatness!!

SPB 100 Circuit Breaker Handle Broken ?

One of the most common repairs we receive with regard to Cutler Hammer Westinghouse SPB circuit breakers is for replacement charging handles.

I would say 90% of the time its not just the operating handle that is broken, but also the SPB hub assembly as well.

You will notice the handle is missing from the right side of this SPB 100 ,  4000 amp circuit breaker. Upon closer inspection you can see that the hub assembly is actually broken as well.

The handle is attached by two screws to the hub assembly. You will need to inspect the area where it attaches to determine if the plastic hub is damaged as well. It almost certainly will need to be replaced.
