Can different phases be connected to a switch actuator?
Different phases can be connected to the switch actuator in principle, e.g. L1-L2-L3.
For switch actuators with separate floating switching contacts, e.g. SA/S 4.16.2.1, different phases can be switched side by side.
This is also ensured for switch actuators with a common power supply for several channels.
