  • the information store is located on the outside of the Housing of the overcurrent release and is releasably attached to this.
  • By attaching the information store to the overcurrent release is achieved in a test of a Overcurrent release after its removal from the circuit breaker also included the information store and possible errors are also recorded.
  • an exchange the current transformer of the circuit breaker also the information store exchange or adapt its programming is.
  • An arrangement according to similar measures is required EP 0 493 272 B1, in which a switch-resistant interface card is provided with the one hand the current transformer and the other the overcurrent release must be connected.
  • the information store is part of a on the connecting line attached first component of a two-part Plug device is, the second component of the overcurrent release heard.
  • resistors are the most reliable and simplest belong to electrical components, it seems advantageous to form the information store by means of resistors. These resistors can expediently be located between contact pins switched the first component of the connector his. If, for example, four characteristic property values are to be coded, z. B. the rated current of the circuit breaker, its size, the switching power class and the standard class, a resistor can be provided for this, its resistance value between about 1 ⁇ and about 1 M ⁇ lies, with the resistance values specified levels of the above Property characteristics are assigned. Within the mentioned range of resistance values can be based on this For example, 16 different values without errors establish.

This range of resistances can, for example, be divided into 16 values that are recognized without errors.

Abstract

L'invention concerne un interrupteur électrique de puissance (1) présentant un déclencheur électronique à surintensité (4) pour traiter des signaux d'un détecteur de courant (6). Afin de raccorder le détecteur de courant (6) au déclencheur à surintensité (4), il est prévu une ligne de raccordement flexible (5) à l'extrémité de laquelle est placé un premier composant (10) d'un dispositif d'enfichage en deux parties, dont le deuxième composant (11) fait partie du déclencheur à surintensité (4). Des résistances (12, 13, 14, 15, 16) sont placées dans le premier composant (10) entre des broches de contact (17) pour coder des caractéristiques individuelles ou des combinaisons de ces caractéristiques, par exemple l'intensité nominale ou la classe de pouvoir de coupure.
