9.2.2 Remoto Operation

4. Electrical operation
Closing operation is done by charging the closing spring from remote control. If pushing OFF button, closing
spring is automatically charged by a geared motor and a circuit breaker is closed by ON button.
5. Electrical closing
Remote closing can be made by energizing the closing coil (CC). Apply the rated voltage to A3+ and A4- of
the control circuit terminalsand close the circuit breaker.
6. Electrical opening (Tripping)
a) Remote opening can be made by energizing the Opening coil (SHT) or the Under Voltage Coil (UVT) device.
b) In the case of SHT, apply the rated voltage to A5+ and A6- of control circuit terminals.
c) In the case of UVT, remote opening is possible by connecting the switch in series to D1+ and D2-,
terminals of UVT coil.

9.2.3 High-speed reclosing operation

This operating mechanism is available for the high-speed reclosing (O-0.3s-CO) operating duty by remote operation
at the status that the main circuit is "CLOSE" and the closing spring is "CHARGED".
To perform the operating duty of multiple auto reclosing (O – 0.3s – CO – 15s – CO), the closing spring shall be
