    Circuit Breakers - New, Used, & Obsolete

    Circuit breakers are the heart of any electrical system, as they are responsible for halting the flow of electricity in case of fault or overload. When they fail, they can cause major disruptions. Bay Power can help minimize the disruptions by getting you the breaker you need, quickly. Whether it be molded case breakers, air breakers, insulated case breakers, or vacuum breakers, we can deliver. 

    We Carry Breakers from all the Top Manufacturers

    Circuit breakers come in a number of shapes, sizes, and brands - while many are available brand new, there is a wide range of obsolete circuit breakers that are no longer in production, many of which are available as reconditioned. The options may seem endless, but once you know your requirements and specifications, it is easier to make the right decision. If you need help identifying the breaker you need, give us a call or send us a note. Our experts can help you come to the right decision, depending on its residential or industrial use.

    Choose Bay Power for all your circuit breaker needs.

    Bay Power carries a wide variety of different circuit breakers, circuit breaker accessories and circuit breaker enclosures. We’re proud to offer a variety of residential, molded case, insulated case, air, vacuum, low and medium voltage circuit breakers, both new and reconditioned. Choose a manufacturer or circuit breaker type below:

    Air Circuit Breakers

    Air Circuit Breakers

    Air circuit breakers provide overcurrent protection for 800 – 1000A circuits. They are most commonly used in low and medium voltage applications. Unlike molded case circuit breakers, these are completely open making them easily adjustable. Since they are completely open, they are also easily reconditioned. Bay Power carries a wide variety of both new and reconditioned air circuit breakers.

    Insulated Case Breakers

    Insulated Case Breakers

    Insulated case circuit breakers can do everything a molded case circuit breaker can, except they contain a 2-step stored energy mechanism. Most commonly used in low voltage circuit breaker applications, insulated case circuit breakers use special insulating material when interrupting circuits. Insulated case circuit breaker frame sizes can range anywhere from 800-5000A.

    Molded Case Circuit Breakers

    Molded Case Circuit Breakers

    Molded case circuit breakers protect against overloads, short circuits, and ground faults by using one or a combination of electromagnetic and/or thermomagnetic trip mechanisms. Molded case circuit breakers are exceptionally durable, can break larger currents, and can also be adjusted to trip for lower amounts.
    Vacuum Circuit Breakers

    Vacuum Circuit Breakers

    Thanks to their arc-extinguishing vacuum chamber, vacuum circuit breakers are some of the most reliable circuit breakers around. Using this highly effective arc-extinguishing mechanism, they require much less maintenance and last much longer than their counterparts. However, they are most effective and most commonly used for medium voltage circuit breaker applications (33 kV - 66 kV).

    Low Voltage Circuit Breakers

    Low voltage circuit breakers, also referred to as LV circuit breakers, are used in low voltage applications that are rated at 600 volts or less. The most common types of low voltage circuit breakers include molded case circuit breakers, miniature circuit breakers, and low voltage power circuit breakers.

    Medium Voltage Circuit Breakers

    Used in heavy industrial and commercial applications, medium voltage circuit breakers are commonly heavy-duty bolt-on breakers, and are intended to specifically handle medium voltage equipment (ranging from as low as 1kV to 72kV). While we don’t display our medium voltage circuit breakers on our website, if you’re interested in a medium voltage breaker, please give us a call.
    Mini Circuit Breakers

    Mini Circuit Breakers

    Miniature circuit breakers (UL 489-rated), also known as DIN rail circuit breakers, are a small type of molded case circuit breaker. They are often used to break small currents as they can be reset, unlike a fuse that would need to be replaced, and are most commonly found in residential lighting circuits, industrial kitchen appliances, air conditioners, and more.

    Industrial Circuit Breakers

    Industrial Circuit Breakers

    Industrial circuit breakers are designed specifically with industrial applications in mind. They are built specifically to withstand the pressures, and protect the circuits of, heavy duty industrial applications that are not found in residential or commercial sectors. The most common circuit breakers used in industrial applications include molded case circuit breakers, air circuit breakers, and sometimes even miniature circuit breakers.

    Residential Circuit Breakers

    Residential Circuit Breakers

    There are many types of residential circuit breakers that can be found in your home, depending on where it is installed and in what room. From GFCIs to AFCIs, single pole and double pole, you can count on us to provide you with not only with the right type of residential breaker, but peace of mind as well.

    Breaker Accessories

    From undervoltage releases to breaker handle ties, shunt trips to rating plugs, trip units and lugs, your circuit breaker accessories are just as important as the circuit breakers themselves. Choosing the right circuit breaker accessories will help protect your electrical system and your circuit breakers, as well as extend their lifespan.
