Definitions

  • the invention relates to a low-voltage circuit breaker with a rated current plug, by means of which the electronic trip unit of the circuit breaker can be adapted to the conditions of its place of use. If an unsuitable rated current plug is used, the evaluation device of the trip unit adjusts to minimum setting values and by means of a signaling device a message is issued.
  • Circuit breakers in the low voltage range should be in the widest possible nominal current range, e.g. B. 200 A to 6300 A, can be used. Your rated current should therefore be selectable. With the setting of a certain rated current, the respective overcurrent release is parameterized to a selected nominal current. The overcurrent release can thus have the same design for the entire nominal current range.
  • Such a rated current plug is known, for example, from US Pat. No. 4,649,455. If the rated current plug is removed from the switch according to this solution, e.g. B. to him against a rated current plug with changed setting values the tripping unit automatically sets itself to a minimum tripping value until a rated current plug has been inserted again. In the simplest case, this is achieved in that a setting resistor, which is electrically connected in parallel to the setting resistors in the rated current plug, is fixed in the tripping unit and determines the rated current when the rated current plug is removed.
  • the object of the invention is to further increase the safety of circuit breakers with regard to the use and the function of rated current plugs suitable for the circuit breaker and to have to deal with the expense of mechanical coding. According to the invention the object is achieved by the features of claim 1. Appropriate embodiments are the subject of the subclaims.
  • the signaling device is then arranged on the housing of the low-voltage circuit breaker or on the tripping unit.
  • the signaling device can be in the same manner as in DE-A 198
  • 45 825 shown an acoustic and / or optical signal transmitter, for. B. a flashing light emitting diode.
  • a circuit 12 is monitored with a circuit breaker 1, so that in the event of impermissible current values via contacts 2, actuated by a drive device 3, a switch-off takes place.
  • the current in the circuit 12 is measured with a current sensor 4. Its measured value is processed in a tripping unit 5.
  • the trigger unit 5 consists of a microprocessor 6, a reading device 7 and one Evaluation device 8. In the housing of the circuit breaker
  • the rated current plug 9 contains the coding for the rated current and possibly further values, in the simplest case in the form of resistors of a defined size.
  • the values read by the reading device 7 are compared with the permissible values of the circuit breaker 1 concerned. If these are within permissible limits, they are taken over by the trigger unit 5. If, on the other hand, there are no permissible values because, for example, the rated current plug 9 has been removed, the triggering unit 5 emits a pulsating signal to an LED 10. LED 10 then flashes and reports an error condition to the user. At the same time, the setting values of the tripping unit 5 are changed to minimum values. The message and the minimization of the setting values remain effective until a permissible rated current plug is inserted again.
  • a signaling device can also be integrated directly into the tripping unit 5.

Abstract

Un calibreur est généralement équipé d'un codage électrique, de manière à empêcher la transmission de valeurs caractéristiques incorrectes du calibreur à l'unité de déclenchement et à entraîner l'émission d'un signal lors d'une tentative d'utilisation dudit calibreur. Selon la présente invention, le dispositif de signalisation est agencé sur le boîtier du disjoncteur basse tension (1) ou sur l'unité de déclenchement (5). Ainsi, par rapport à la solution classique, les états 'calibreur incorrect', 'liaison de contact défectueuse', 'calibreur défectueux' sont également détectés.
