    Medium voltage. Heavy duty.

    Medium voltage circuit breakers are heavy-duty, bolt-on breakers intended to protect and switch electricity for medium voltage equipment (ranging from as low as 1kV up to 72kV). Used in heavy industrial and commercial applications like power plants, both vacuum circuit breakers and air circuit breakers are the most common types of medium voltage breakers.

    While both can get the job done and are rated up to 6,300A and higher, vacuum breakers tend to be the more popular choice due to their longer life span as well as their highly efficient arc-extinguishing mechanism. Air breakers, however, do have the advantage of being fully adjustable and more easily modified. Medium voltage breakers are also often built with draw-out construction, which allows them to be removed easily without disrupting any of the other circuits in the system.

    Choosing the right medium voltage circuit breaker.

    Understanding your circuit breakers needs is crucial to getting the breaker that’s right for you and your electrical system. Knowing the frame size, the continuous current, rated voltage, interrupting capacity and the number of poles can go a long way when you buy your medium voltage circuit breaker.
