Circuit Breaker Sales NE supplies a wide range of new, surplus, and remanufactured low-voltage circuit breakers of all types and from all OEMs. Here are three things to determine to make sure you’re purchasing the correct air circuit breaker:
Model and/or type: You don’t necessarily need to know the manufacturer but rather the type, which is written on the front name plate. For example, if the name plate says “AK-2-25,” we can check our vast inventory to determine that GE is the manufacturer.
Draw–out versus bolt-in: Air circuit breakers are either draw-out, meaning they rack out of their cells, or bolt-in, which means they bolt into their cells. Draw-out breakers are much easier to handle because you can rack them out with a racking tool. With a bolt-in circuit breaker, you have to unbolt it from the rear bus that connects to the back of the breaker. The difference between these is visual. Inspect your model to see which type of breaker you have, or take a picture and send it to us for identification.
Manual or electrical operation: Manually operated circuit breakers always have a handle, similar to a large pistol grip. Electrically operated circuit breakers usually have a charging motor, a relay, and a shunt trip unit. It is important to know the close and trip voltage and, if possible, to have a wiring diagram for the breaker.
Even if you don’t have any of this information, the experts at Circuit Breaker Sales NE can tell you the exact breaker type and which replacement parts you need.
