circuit breaker, breaker teriminin İngilizce İngilizce sözlükte anlamı

circuit breaker
An electrical switch capable of opening and closing an electrical circuit in all operating conditions, including fault situations
circuit-breaker
Alternative spelling of circuit breaker
residual current circuit breaker
(Elektrik, Elektronik) A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the flow of current is not balanced between the phase ("hot") conductor and the neutral conductor. The presumption is that such an imbalance may represent current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A shock, possibly lethal, is likely to result from these conditions; RCDs are designed to disconnect quickly enough to prevent such shocks

circuit breaker
A circuit breaker is a device which can stop the flow of electricity around a circuit by switching itself off if anything goes wrong. There is an internal circuit breaker to protect the instrument from overload. An automatic switch that stops the flow of electric current in a suddenly overloaded or otherwise abnormally stressed electric circuit. a piece of equipment that stops an electric current reaching a machine if the machine becomes dangerous
circuit breaker
Device in a circuit that opens the circuit, preventing the flow of electricity, so that it will not be damaged by an overload or short
circuit breaker
A switch on an incoming power circuit that opens if abnormal circuit conditions arise (such as an overload or short circuit)
circuit breaker
a device that trips like a switch and opens the circuit when overloaded
circuit breaker
Device used to open and close circuit by non-automatic means, as well as to open circuit automatically on predetermined overload current without injury to itself (when properly applied within its rating)
circuit breaker
A re-settable protection device that amounts to a fuse that never needs replacement (e g , My stereo shop got tired of replacing 50 amp fuses in my system so they went ahead and installed a 50 amp circuit breaker )
circuit breaker
Device that interrupts current if a circuit is overloaded or a short occurs Unlike a fuse, it can be reset
circuit breaker
A safety device in an electrical circuit that automatically shuts off the circuit when it becomes overloaded
circuit breaker
A resetable fuse for an electrical circuit   See fuse
circuit breaker
A device which looks like a switch and is usually located inside the electrical 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 rating of 15 or a maximum of 20 amps '220' volt circuits may be designed for higher amperage loads e g a hot water heater may be designed for a 30 amp load and would therefore need a 30 amp fuse or breaker also see GFI
circuit breaker
Safety device which automatically opens an electrical circuit if overloaded
circuit breaker
The most common type of "overcurrent protection " A breaker trips when a circuit becomes overloaded or shorts out
circuit breaker
An automatic, magnetic, or bimetallic device that will open a current-carrying circuit causing the circuit to become inoperative This device is used to prevent circuit damage under a condition of excess current Unlike a fuse that melts when its rating is exceeded, a circuit breaker can be reset automatically or manually when the circuit problem is corrected
circuit breaker
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
circuit breaker
CIRCUIT BREAKERS automatically stop the flow of electricity when it senses too much current or an abnormal condition Circuit breakers are located in substations and on transmission and distribution lines throughout Duquesne Light’s system Once a circuit breaker opens, it must be reset before the flow of power can be restored
circuit breaker
A procedure that temporarily halts trading on all U S stock markets for one hour when the Dow Jones Industrial Average falls 250 points or more within a trading day The pause is designed to allow time for the markets to absorb the news that precipitated the decline Should the average fall another 150 points within the same day, trading would again be halted, this time for two hours
circuit breaker
Simple switch-like device which automatically opens a circuit when the rated current is exceeded as in the case of a short circuit
circuit breaker
A mechanically resettable unit that disconnects a circuit at a specifically defined current
circuit breaker
-A device that can be used to manually open or close a circuit, and to automatically open a circuit at a predetermined level of overcurrent without damage to itself
circuit breaker
A switch that automatically disconnects power to the circuit in the event of a fault condition Located in substations Performs the same function as a circuit breaker in a home BACK TO TOP
circuit breaker
The overcurrent protection device (OCPD) most commonly in residential use The circuit breaker can be opened and closed repeatedly to allow or stop power from flowing along the branch circuit Back to alphabetical list
circuit breaker
a device which detects excessive power demands in a circuit and self-interrupts when they occur
circuit breaker
- A reset-able protection device that stops the flow of current when amperage in excess of it's rating flows through it
circuit breaker
A resettable device that responds to a preset excess of current flow by opening the circuit thereby preventing damage to circuit elements
circuit breaker
A system of trading halts and price limits on equities and derivative markets designed to provide a cooling-off period during large, intraday market declines The first known use of the term circuit breaker in this context was in the Report of the Presidential Task Force on Market Mechanisms (January 1988), which recommended that circuit breakers he adopted following the market break of October 1987
circuit breaker
an automatic switch which operates like a fuse and interrupts a circuit under an infrequent abnormal condition [return to top]
circuit breaker
An automatic switch that operates like a fuse and interrupts a circuit when too strong an electric current is passing through
