5 Types of Circuit Breakers Standard, Single-Pole Breaker. A single-pole breaker protects a single circuit in your home’s electrical system. This Standard, Double-Pole Breaker. Double-pole breakers work the same way as single-pole breakers, but they protect circuits Ground Fault Circuit See more
Learn MoreDec 19, · The very first circuit breaker was devised in 1879 by Thomas Edison, when he came up with the idea of protecting circuit wiring used for lighting from the common problems of current overloads and short circuits. Of course, we now know that his system suffered from the fatal flaw of using fuses that would need to be constantly replaced.

Learn MoreThere are three types of Square D circuit breakers: The Homeline QO (plug-on) QOB (bolt-on) circuit breakers. All square D circuit breakers have Ground Fault Circuit Interrupter (GFCI), Arc Fault Circuit Interrupter (AFCI), and a combination Arc-Fault Circuit Interrupter or the CAFI breakers.
Learn MoreInside, look for the name Stab-Loc (the brand name of the circuit breakers). Zinsco Panels Zinsco or GTE-Sylvania panels were popular electrical panels installed in homes throughout the 1970s. Zinsco is now defunct, but many homes still have these panels. Why they’re unsafe: The circuit breakers inside many Zinsco panels melt to the main ‘bus bar’.
Learn MoreThe Air blast circuit breaker employs a high-pressure air blast as an arc extinguishing medium. This type of circuit breaker is used in open terminal HV applications with a voltage range of 245 kV, and 400 kV up to 765 kV, especially where fast breaker operation is required. Compared to SF 6 and vacuum type, air blast circuit breaker is rarely
