  • Types of Circuit Breakers - The Home Depot

    GFCI Circuit Breakers Ground fault circuit interrupter (GFCI) circuit breakers cut power to the entire circuit. They are tripped by an overload of current, a short circuit or a line-to-ground fault. This can occur when an unwanted path forms between an electrical current and a grounded element.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.

  • Circuit breaker - Wikipedia

    Gas (usually sulfur hexafluoride) circuit breakers sometimes stretch the arc using a magnetic field, and then rely upon the dielectric strength of the sulfur hexafluoride (SF 6) to quench the stretched arc. Vacuum circuit breakers have minimal arcing (as there is nothing to ionize other than the contact material).

  • AC High Voltage Circuit Breakers - IEEE Web Hosting

    High-Voltage Circuit Breaker The main task of a circuit breaker is to interrupt fault currents and to isolate faulted parts of the system. A circuit breaker must also be able to interrupt a wide variety of other currents at system voltage such as capacitive currents, small inductive currents, and load currents.
