1 Connection with vacuum electromagnetic contactor for capacitor switching.
This device has a constant excitation system that outputs no-voltage
continuously ON at connection and continuously OFF at disconnection as a cap acitor control signal.
Upon connecting with the vacuum electromagnetic contactor for capacitor switching
auxiliary relay. (Refer to the connection with auxiliary relay C
Use the counter electromotive force absorption diode built-in relay as the auxiliary relay for DC (
2 Reversed Phase
This device operates on reversed phase without changing the wire connections.
3 Forced Disconnection Signal
When ON signal is input on the forced disconnection signal terminal TB and terminal TA/S
connecting capacitors in automatic control are disconnected.
When OFF signal is input on terminal TB and TA/S
Use input contacts suited for the switching of
*This signal can be used for the following applications.
To disconnect the capacitor by an external time switch for purpose
of avoiding leading-out of power factor during night time.
