According to the IEC, the motor shall work between 85 % and 110 % of nominal voltage. Minimum pick-up: Determines the minimum voltage necessary to trip and close the breaker and verifies whether it can reliably operate in the event of a low DC supply.
Essential elements of a breaker include the interrupter unit, the mechanical linkage, and the operating mechanism with an energy storage system. The energy that is needed to operate a circuit breaker is high, and it must be made available within a few milliseconds, i.e. almost instantaneously.
While old medium voltage circuit breakers often used oil as interrupting medium, in modern times vacuum is the preferred medium and is thus almost exclusively used. Essential elements of a breaker include the interrupter unit, the mechanical linkage, and the operating mechanism with an energy storage system.
The rated service short-circuit breaking capacity of a circuit breaker is the maximum short-circuit current value which the circuit breaker can break three times, in accordance with a sequence of opening and closing operations (O - t - CO - t – CO), at a defined rated operational voltage (Ve) and at a defined time constant (for direct current).
This represents the value of current of the trip unit mounted on the circuit breaker and determines the protection char-acteristic of the circuit breaker itself according to the avail-able settings of the trip unit. This current is often referred to the rated current of the load protected by the circuit breaker itself.
The rated ultimate short-circuit breaking capacity of a circuit breaker is the maximum short-circuit current value which the circuit breaker can break twice (in accordance with the sequence O – t – CO) at the corresponding rated opera-tional voltage.
