A circuit breaker is an automatically operated switch in your furnace or HVAC system that's intended to prevent damage from happening to the internal components, because of an extraneous or unpredictable current. If something goes wrong with your HVAC device, then your circuit breaker could be the component that keeps you and your family safe. At Furnace Part Source, we offer a collection of reliable circuit breakers, perfect for almost any project.

Achieving HVAC Safety with Circuit Breakers

When an excess current occurs within an electrical heating or cooling system because of an overload or wiring problem, your circuit breaker interrupts the current flow and prevents any additional damage. Not only does it protect the inside of your furnace, but it can also reduce the risk of dangerous sparks, fires, and other potentially home-destroying problems.

At Furnace Part Source, you can find a wide selection of competitively priced circuit breakers designed to suit any project, from some of the most popular brands on the market, like Carrier and Trane. Browse our collection today and choose the component that's right for you. Remember, you can enjoy same-day shipping and international delivery on a wide selection of Furnace Part Source products!
