Switch-plug combination with zero voltage release for AC-motors up to 3 kW.
the connection of the switch is made with the open base.
When the voltage drops, the switch actuates, therefore a connected device can not turn itself back on when the power recovers.
Fitting capacitors can be found at the catalog "replacement parts" at Operating capacitor.
The right capacitor capacity can be found as specification in microfarad (µF) on the capacitor or the type plate of the motor.
