- Page 17 The vacuum inter- rupters work synchronously in the same direction. The solenoid actuator and the shunt release of the vacuum contactor 3TM can be actuated with AC or DC. Vacuum contactors 3TM work according to a defined closing and opening time, which can be configured and extended by an additional closing and opening delay.
- Page 18 Description Fig. 9 Terminals A1/A2 and optionally E1/E2 of the electronic controller The electronic controller also allows the configuration of additional closing and open- ing delays. If no configuration is selected, only the natural closing and opening time of the switching device is active. The configuration is delivered ex works according to the option ordered.
