15 Kv Power Circuit Breaker, Perfect Scrap

FOR IMMEDIATE RELEASE
milwaukee, Wisconsin, United States of America (Free-Press-Release.com) September 16, 2011 --

For an Electrical Power Engineer, it may seem strange to see someone tearing apart a 15 Kv GE magna blast circuit breaker for scrap. They are one of many work horse high voltage air circuit breakers used successfully for decades in manufacturing plants across the Country. But they have been replaced with 15 kv vacuum circuit breakers. Vacuum breakers are reliable, fast acting, low maintenance devices. Many air circuit breakers have been retrofitted with vacuum circuit breakers. The old air circuit breakers are being scrapped because there are just so many on the secondary market and many are not in good condition. They might look great, be in good mechanical condition, but the arc chutes may have serious damage or dielectric deterioration. These things are not noticeable to most people, but MIDWEST tests high voltage circuit breakers and looks can be extremely deceiving. In addition, the cost to recondition an air circuit breaker is very high. It’s not just the mechanics of the circuit breaker, but the dielectrics can be far more costly. The old GE General Electric and Westinghouse high voltage air circuit breakers are everywhere in the secondary market and they sit for years on the storage shelves. If we have 40 GE General Electric 1200 amp magna blast circuit breakers and we sell 5 a year and we can buy as many more as we need, at little cost, then their value today may be greatest as scrap. This is especially true with the value of scrap metal, like copper, being so high. It’s not 1970 any more.
