for recording energy consumption and various electrical variables in the final circuit. Various electrical variables can be monitored by threshold values and load peaks can be limited by simple load control. The recorded values are made available via ABB i-bus KNX. The electrical consumers (alternating or three-phase current) connected via potential-free independent contacts can be switched via ABB i-bus KNX or manually using a switch toggle. The energy actuator is particularly suitable for switching ohmic, inductive and capacitive loads. The switching capacity corresponds to the C-Last SA/S X.16.6.1 switching actuators.
