  1. Mar 5, 2024 · A circuit breaker is an electrical safety device. It's essentially a resettable fuse that's an automatically operated electrical switch designed to interrupt current flow whenever the current jumps above a safe level, avoiding overheating, melting, and potential fires.

  2. A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire.

  3. All types of circuit breakers interrupt electrical flow to prevent fires and protect electronic equipment. Use this guide to learn how to select circuit breakers.

  4. Jun 18, 2023 · Circuit Breaker Definition: A circuit breaker is a manually or automatically operated electrical switch designed to protect and control power systems by interrupting fault currents.

  5. By definition a circuit breaker is an electrical safety device, a switch that automatically interrupts the current of an overloaded electric circuit, ground faults, or short circuits.

  6. Jun 23, 2022 · Circuit breakers protect electrical circuits by cutting off the flow of electricity when they detect too much current on the circuit. This “overcurrent” can be caused by having too many things plugged in at once or a sudden surge of electricity known as a short circuit or ground fault.
