Circuit-breaker
A mechanical switching device, capable of making, carrying and breaking
currents under normal circuit conditions and also making, carrying for a specified
time and breaking currents under specified abnormal circuit conditions such as
those of short-circuit.
Current-limiting circuit-breaker
A circuit-breaker with a break-time short enough to prevent the short-circuit
current reaching its otherwise attainable peak value.
Plug-in circuit-breaker
A circuit-breaker which, in addition to its interrupting contacts, has a set of
contacts which enable the circuit-breaker to be removed.
Withdrawable circuit-breaker
A circuit-breaker which, in addition to its interrupting contacts, has a set of
isolating contacts which enable the circuit-breaker to be disconnected from
the main circuit, in the withdrawn position, to achieve an isolating distance in
accordance with specified requirements.
Moulded-case circuit-breaker
A circuit-breaker having a supporting housing of moulded insulating material
forming an integral part of the circuit-breaker.
Disconnector
A mechanical switching device which, in the open position, complies with the
requirements specified for the isolating function.
Release
A device, mechanically connected to a mechanical switching device, which
releases the holding means and permits the opening or the closing of the
switching device.
Fault types and currents
Overload
Operating conditions in an electrically undamaged circuit which cause an overcurrent.
Short-circuit
The accidental or intentional connection, by a relatively low resistance or
impedance, of two or more points in a circuit which are normally at different
voltages.
Residual current (I∆)
It is the vectorial sum of the currents flowing in the main circuit of the circuitbreaker.
