Switch Actuators AKI industry


The industrial version of the MDT Switch Actuator AKI for large to very large loads is used where particularly high inrush currents are to be expected. The actuator is equipped with bistable relays for currents up to 16/20 A and a C-load up to 200 µF. Thanks to mechanical manual operation, they are particularly suitable for sensitive areas. The channels can also be switched without bus voltage and the switching status is visible at all times.
