An electrical circuit breaker is an automatic safety switch that operates by measuring heat or current flowing through the circuit. If the current exceeds the pre-set limit of the circuit, it will trip or sever the electrical supply. Electrical circuit breakers are absolutely essential to any electrical system. They protect appliances, wiring, and electronics from abnormal surges in electricity. Without them, there’s a risk of overloading the circuit and causing a fire or other electrical hazards. This can have devastating effects on commercial and industrial buildings and potentially endanger lives.

If you need industrial or commercial circuit breakers, Tanooga is the place to get them. The circuit breakers we sell are reliable, durable, and affordable. For more information on our electrical circuit breakers, give us a call at 423-771-7102 or send an email to [email protected].
