10 1 Fig. Circuit-breaker rating plateFig. 3 Selective General characteristicsThe SACE Emax series of circuit-breakers consist of a steel sheet structure which houses the operating mechanism, the poles and the auxiliaryparts. Each pole, insulated from the others, contains the interrupting parts and the current transformer of the corresponding structure of the poles differs according to whether the circuit-breaker is selective or current limiting. The fixed version circuit-breaker hasits own terminals for connection to the power circuit. In the withdrawable version, the circuit-breaker makes up the moving part of the apparatus,which is completed with a fixed part fitted with the terminals for connection to the power circuit of the installation.
