Definitions

  • the present invention relates to a three-phase circuit breaker as defined in the preamble of claim 1.
  • It also relates to a differential circuit breaker having a three-phase circuit breaker connected to a quadruple adaptable differential block.
  • the series combination of a circuit breaker and a differential block forms an electrical assembly called a differential circuit breaker.
  • the circuit breaker provides protection for electrical devices powered by an electrical circuit downstream of this circuit breaker against short circuits that produce a sudden increase in current. When such an increase in current occurs, the circuit breaker interrupts said electrical circuit, which puts the electrical appliances powered by this electric circuit off.
  • the adaptable differential block is used to protect people against insulation faults that can not be detected by switchgear such as circuit breakers or switches.
  • the adaptable differential block measures the value of the current flowing through each phase and neutral conductor of the electrical network. If a person comes into direct contact with a live part of the electrical network, the adaptable differential block detects a difference between the current values in the above-mentioned conductors. If this difference exceeds a predetermined threshold value, the adaptable differential block triggers the associated circuit breaker which interrupts the electrical circuit so as to ensure the safety of the person in contact with this electrical circuit.
  • circuit breakers and these adaptable differential blocks are modular electrical devices whose width is a multiple of the width of a basic module which is of the order of 18 millimeters.
  • four-phase circuit breakers commonly have a width equal to four times the width of a base module to house four electrical connection terminals including three phase terminals and a neutral terminal
  • three-phase circuit breakers commonly have a width equal to three times the width of a base module to house three connection terminals live electrical.
  • the adaptable differential blocks intended to be associated with each of these two types of circuit breaker have a specific shape.
