ABSTRACT:
A remotely controlled circuit breaker or switch comprises two breaking poles adjoining a remote control unit with an electromagnet, and a toggle for manual operation of the contacts. The remote control unit comprises a selector switch for switching into the electronic circuit a position detector of breaker contacts, four connection terminals, and an electronic power supply circuit for an electromagnet. Two of the input terminals TL (inpulse relay mode) and CT (contactor mode in the active position of the selector switch), are accessible simultaneously with the existence of a priority code between the two controls and of a refresh function of the statuses of the electronic circuit. The latter allows forced manual operation by means of the toggle.
