Low-voltage circuit breaker comprising a data memory

摘要

Data memories are used to represent the characteristic values of the properties of the circuit-breaker (10) and the associated current transformer (17). Known assemblies requires a large number of plug and socket connections and are limited with regard to the number of parameters that can be stored. The inventive assembly uses a writeable electronic memory module which is inserted into one of the interconnecting cables (1) between the current transfomer(s) and the overcurrent trip (18) as the data memory.
