Consumer unit. Electrical switch. Earthing systems. v. t. e. 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.
Circuit breaker is a design pattern used in software development. It is used to detect failures and encapsulates the logic of preventing a failure from constantly recurring, during maintenance, temporary external system failure or unexpected system difficulties. Circuit breaker pattern prevents cascading failures particularly in distributed ...
In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker.

The 2020–21 Singapore circuit breaker measures were a stay-at-home order and cordon sanitaire implemented as a preventive measure by the Government of Singapore in response to the COVID-19 pandemic in the country on 7 April 2020. The measures were brought into legal effect by the Minister for Health with the COVID-19 (Temporary Measures ...
The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI) or arc-fault detection device ( AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can ...
Trading curb. A trading curb (also known as a circuit breaker [1] in Wall Street parlance) is a financial regulatory instrument that is in place to prevent stock market crashes from occurring, and is implemented by the relevant stock exchange organization. Since their inception, circuit breakers have been modified to prevent both speculative ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating an improper flow of current such as leakage current to ground or current flowing to another powered ...
