A device contained within an electrical circuit designed to interrupt the circuit when the current exceeds a preset value; it is sometimes called a contact breaker. Its function is to prevent fire or damage to the circuit or the devices on the circuit which could be caused by excess current, such as that caused by a short-circuit. It differs from a fuse in not having a conducting element which melts (see 2nd fuse, n.). Circuit breakers are designed to be easily reset, i. e. to reclose the circuit after it has been opened by the circuit breaker; this is usually accomplished by simply moving a switch back and forth. They are commonly used in buildings to protect individual electrical lines, and are often contained in groups within a box called a circuit breaker panel, which divides the current from a main electrical line into multiple circuits each protected by a separate circuit breaker. Less commonly they may be found on individual devices.

After the share market crash of 1987 in U.S., share and commodities exchanges established a system of trigger-point rules, known as circuit breakers, to temporarily restrict trading in shares, share options, and share index futures when prices fall too far, too fast. Circuit breakers have been established in Indian securities market also. Generally, circuit breakers are put up for individual shares and the manner of restrictions vary, depending on the rules framed from time to time. Currently, trading on the New York Stock Exchange (NYSE) is halted when the market, measured by the Dow Jones Industrial Average (DJIA), drops 10% any time before 2:30 p.m., sooner if the drop is 20%. But trading could resume, depending on the time of day the loss occurs. However, if the DJIA drops 30% at any point in the day, trading ends for the day. The actual number of points the DJIA would need to drop to hit the trigger is set four times a year, at the end of each quarter, based on the average value of the DJIA in the previous month.
