ABSTRACT:
The present invention relates to a power circuit-breaker with remote-controllable operation threshold.
The switching out of the circuit-breaker 1 being provided by an electro-magnetic release 2, there is foreseen at least one captor 9a to 9f for detecting a predetermined position of the control element 3 of the release sensitive to the intensity consumed, and said captor sends, when said position is reached, and under the control of a centralized remote-control receiver 11, the control current to the release 2.
The invention is applicable to the modulation of the consumable power by the users and its adaptation to the production capacity.
