Princeton's WordNet

  1. circuit breaker, breaker(noun)

    a device that trips like a switch and opens the circuit when overloaded


  1. circuit breaker(n.)

    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.


  1. circuit breaker(Noun)

    An electrical switch capable of opening and closing an electrical circuit in all operating conditions, including fault situations.


  1. Circuit breaker

    A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high-voltage circuits feeding an entire city.

The Standard Electrical Dictionary

  1. Circuit Breaker

    Any apparatus for opening and closing a circuit is thus termed, but it is generally applied to automatic apparatus. A typical circuit breaker is the hammer and anvil of the induction coil. (See Induction Coil; Anvil.) Again a pendulum connected to one terminal of a circuit may swing so as to carry a point on its lower end through a globule of mercury as it swings, which globule is connected to the other terminal. A great many arrangements of this character have been devised. Synonym.--Contact Breaker.
