Sometimes MIDWEST’s Engineering Technicians in our Switchgear Shop like to do what the Engineers call “Play.” The technicians call it serious research. Sometimes their adventures are quite worthwhile, even enlightening. Recently an Engineering Technician dropped a circuit breaker test form on an Engineer’s desk and said, “Would you take a look at that and tell me if you think it’s okay.” The test results were excellent. The contact resistance, insulation resistance, over current test results, reset tests, all the test results were excellent. So why in the world was the Engineering Technician dropping it on the Engineer’s desk when the test results were so good? The results looked like those for a new circuit breaker. What they had done was test an old Westinghouse circuit breaker that had been practically crushed. The case was broken and the arc chutes damaged. It looked like it had been dropped from 50 feet and hit on one corner. But, oddly enough, against all reason, it operated mechanically and the test results were all good. But, of course, it failed the visual inspection. When the Technician dragged the Engineer to the Switchgear Shop to evaluate the breaker, everyone had a good laugh. This was good fun and the technical evaluation was unanimous, POJ, Piece of Junk. One of our favorite highly technical terms. In this case it was very obvious. But frequently we find defects in used circuit breakers and in brand new circuit breakers, and other electrical equipment, that would never be revealed by testing alone. That’s why the experience, training and knowledge of the Technicians and Engineers are extremely important. There is no perfect test standard for every POJ.
MIDWEST carries General Electric Circuit Breakers. Whether it’s a new, reconditioned, or used breaker, we are sure we can provide just the breaker you need. We stock thousands of General Electric circuit breakers in our inventory.
MIDWEST reconditions General Electric circuit breakers. Worn or damaged breaker component parts are tested and replaced if necessary as part of our quality control program. Over current devices can be retrofitted with electronic devices to assure state of the art over current protection. A low voltage air circuit breaker is disassembled. Insulating and current carrying members are cleaned and inspected and replaced if necessary. The breaker is reassembled and then put through a rigorous testing procedure to make sure everything properly checks out. The breaker would be tested for contact resistance, insulation resistance, and the over current devices would be tested to ensure they operate in accordance with the manufacturer’s trip curve specifications. Typical basic overcurrent functions would be long time, short time, and instantaneous pick up and trip capabilities. Some breakers contain ground fault capability as well.
Our staff is always excited to take your phone call and answer any General Electric Circuit Breaker questions you may have. We are proud to have served the electrical community since 1977, also the year the first Star Wars movie was released, (no connection between those events). Whatever your circuit breaker needs may be, we are sure we are your best solution. Our engineers have many years of experience with circuit breakers and power distribution equipment and they are always happy to answer any question you may have.
Breakers, an integral component to any electrical circuit, come in many types and sizes. Two common categories are the air circuit breakers, and molded case circuit breakers. Air circuit breakers are comprised of a metal frame which serves as the breaker structure. Attached to the metal frame are the various breaker current carrying and insulation components.
Molded case circuit breakers are comprised of a dielectric compound which acts as an insulation member for the current carrying components of the breaker. The dielectric compound also acts as the frame support for the breaker.
Air breakers are typically larger breakers capable of carrying more current. One advantage of molded case breakers is their lower purchase price. The breakers you find in a home electrical panel are small molded case breakers. Molded case circuit breakers can also be larger current carrying types as well. Today’s molded case breakers can go all the way up to 4000 frame amps.
To check on the lowest prices available for breakers, give us a call. Call us old fashioned, but we still have live people answering the phone. Our office hours are from 7:00am to 6:30pm CST. We are very happy to help you make you breaker problem go away.

Cutler Hammer, a venerable name in breakers, bought out the Westinghouse distribution and controls business unit in 1994. This acquisition included the Westinghouse circuit breaker division. MIDWEST carries many types of Cutler Hammer/Westinghouse breakers. A popular Cutler Hammer breaker is the KDC3250 thermal magnetic breaker. Thermal magnetic refers to the type of over current device of the breaker. The thermal element (heat) is responsible for opening the breaker under an over current (long time) condition. The magnetic part is responsible for opening the breaker in a short circuit (instantaneous) condition.

Sometime in January of 1942, the American intelligence community broke the Japanese code enabling the United States to track what the Japanese were up to. Circuit breakers contain their own type of code also. It may not be as intriguing or as sophisticated as all that, but the circuit breaker code tells its own story. Enter the circuit breakers catalog number. This number is the ID bracelet of the circuit breaker. Take the catalog number of a Square D KAL36200. We know it’s a Square D. The “KA” represents the series of the breaker. The “L” means the breaker has lugs. The “3” indicates the number of poles. The “6” the voltage class (in this case it’s 600 volts). The “200” indicates the frame amperes. So there you have it. The anatomy of a breaker contained in one simple number.
So when you call up with questions about circuit breakers, the catalog number is the key number to know.
