Early Auxiliary Contacts – AUE Early closing auxiliary contacts: these allow the undervoltage release to be supplied before the main con- tacts close, in accordance with IEC 60204-1 and VDE 0113 standards. Early opening auxiliary contacts: these allow any electronic devices connected to the system to be disconnected in advance before the sys- tem is damaged by an overvoltage caused by the circuit-breaker opening. The early opening/closing auxil- iary contacts can be installed inside the direct and transmitted rotary handle operating mechanisms for all the SACE Tmax XT family circuit-breakers except for the XT7 (max two contacts @ 400V): • the cabled version includes 3.28ft long cables (AWG20 cable sections); • a dedicated code is available in the withdrawable version which includes the connector for the moving and fixed parts; For the XT7 with a lever operating mechanism, these are mounted directly on the circuit-breaker.
