Abstract (en)
1. Multi-size branch circuit breaker, inserted downstreams of an energy counter (11) in an alternating distribution network for the supply of an electrical low-voltage installation of a consumer, the size changing of the circuit breaker being remotely controlled by the technical agent by means of a remote control circuit (34) arranged in the housing of the counter, said circuit breaker comprising : a mechanism for manual operating (18, 20) and for automatic tripping when a fault occurs, controlled by a trip relay (22), an intensity sensor (28) to detect the current flowing in each phase conductor (R, S, T) of the network, an electronic assembly for processing the signal emitted by the sensor (28) in order to deliver a tripping order to the relay (22) when said current exeeds a predetermined function, and adjusting means of said signal, comprising a voltage divider resistive bridge (32) arranged between the sensor (28) and the electronic assembly ; the resistive bridge (32) of the circuit breaker being constituted by a series resistance (R9) and a shunt resistance, and the remote control circuit (34) comprising a size switch (CM1) connected electrically with the resistive bridge (32) by a link circuit (40, 42) able to generate the variation of the shunt resistance by operating the size switch (CM1).
Abstract (fr)
L'invention concerne un disjoncteur de branchement à déclencheur électronique dont le changement de calibre est piloté depuis le coffret du compteur (11) par un circuit de télécommande (34). Le pont résistif (32) du disjoncteur est formé par une résistance série (R9) et une résistance shunt variable selon la position d'un commutateur de calibre logé dans le circuit de télécommande (34) et relié au disjoncteur par un circuit de liaison à deux conducteurs (40, 42). Application: Télécalibrage d'un disjoncteur de branchement.
