A device that is designed to protect electrical equipment and people from damage or injury caused by overload or short circuit or a protective switch that automatically switches off, or trips, the power to a circuit in the event of an overload or short in the circuit. It can be reset to resume operation.

 - A device that can be used to manually open or close a circuit, and to automatically open a circuit at a predetermined level of over current without damage to itself.

The general term to describe a mechanical device that breaks the flow of current when it exceeds a set amount. Circuit breakers vary from the small low voltage units found in domestic switchboards, to large outdoor units installed in high voltage switchyards.

A device used to open and close a circuit non-automatically, as well as open a circuit automatically when subjected to a predetermined overload current without damaging itself.

The most common type of "overcurrent protection." A breaker trips when a circuit becomes overloaded or shorts out.

A device designed to open and close a circuit by non-automatic means and to open the circuit automatically on a pre-determined overcurrent without damage to itself when properly applied within its rating.

A switch that opens an electric circuit when a short occurs.

A device designed to open and close an electrical circuit.

the most common type of "over current protection." A breaker trips when a circuit becomes overloaded or shorts out.

A switching device designed to open and close a circuit by non-automatic means and that will automatically interrupt electric circuit under abnormal conditions to prevent harmful, excessive current.

A device that shuts down power when sensing an overload of current.

A device which looks like a switch and is usually located inside the electrical breaker panel or circuit breaker box. It is designed to (1) shut of the power to portions or all of the house and (2) to limit the amount of power flowing through a circuit (measured in amperes). 110 volt household circuits require a fuse or circuit breaker with a ratin [..]

equipment used to open and close circuits to predetermined currents without damage

a device designed to open a circuit either by manual action or by automatic action when current exceeds a value longer than permitted. A circuit breaker can provide overcurrent protection.

      A circuit protection device that opens the circuit automatically when an overload or short circuit occurs.

A switch like device with a pre-set current limit used to protect a circuit from electrical overload. If the circuit breaker is activated (or tripped), it can be reset by pushing a button - however th [..]

 DC circuit breaker that protects the battery of a UPS.

A device that automatically interrupts the flow of an electric current when the current becomes excessive.

A safety device which opens (breaks) an electric circuit automatically when it becomes overloaded.

A safety device that breaks the flow of electrical current whenever a circuit becomes overloaded.

A device designed to open and close a circuit by non automatic means, and to open the circuit automatically on a predetermined overload of current, without injury to itself when properly applied within its rating. (NEC-NFPA No.70)

A device designed to open and close a circuit by non-automatic means and to open the circuit automatically on a pre-determined overcurrent without damage to itself when properly applied within its rat [..]

Used as a safety device instead of fuses in buildings; used to prevent circuits in houses and buildings from being overloaded.

A time-delay circuit interrupter, which opens the circuit when the current flow exceeds the breaker/rating for a short period of time.

A device designed to safely open and close a circuit and protect it from overloads. The device automatically opens the circuit when a predetermined voltage or current occ [..]

A device used to interrupt or break an electrical circuit when an overload condition exists; usually installed in the positive circuit; used to protect electrical equipment.

A circuit breaker is a switching device capable of starting, carrying and stopping electrical currents under normal circuit conditions. It also can start and carry currents for a specified time and st [..]

A device designed to open a circuit and stop the flow of current when the current or voltage in the circuit exceeds a pre-set value.

An electromechanical device designed to quickly break its electrical connection should a short circuit or voltage overload occur. A circuit breaker is similar to a fuse, except the breaker can be manu [..]

An electrical switch that automatically breaks a circuit if the current through it is higher than its rating. Once tripped it can be manually reset. Performs the same function as a fuse, but eliminate [..]

A device that opens an electric circuit when an overload occurs.

A protective device designed to open a circuit (stop the flow electricity) when that circuit is overloaded without damage to the circuit breaker. After automatic actuating, it is reset manually. It is [..]

Every circuit must be protected, circuit breakers break (interrupt) the circuit when it is over loaded. Current causes heat that can cause a fire hazard if circuit breakers are not sized properly to the wiring.
