Spring Charged Operation
Manual charging type
For this type of ACB, the closing springs are charged by means of the spring charging handle. ON/OFF operation of the ACB is
performed by means of ON/OFF buttons on the ACB.
Charging the closing springs
Pumping the spring charging handle by hand charges the closing springs.
Closing the ACB
Pressing the ON button on the ACB closes the ACB.
Opening the ACB
Pressing the OFF button on the ACB opens the ACB.
The ACB cannot be closed as long as the OFF button is pressed.
Motor charging type
For this type of ACB, the closing springs are charged by means of a motor. ON/OFF operation of the ACB can be performed
remotely.
A manual charging mechanism is also fitted to facilitate inspection or maintenance work.
Charging the closing springs
A motor is used to charge the closing springs.
When the closing springs are released to close the ACB, they are automatically charged again by the motor for the next ON
operation.
Closing the ACB
Turning on "remote" ON switch enables the ACB to be remotely closed.
• Anti-pumping mechanism
Even if the ON switch is kept on, ACB closing operation is performed only once.
To close the ACB again, remove the ON signal to reset the anti-pumping mechanism and then reapply the ON signal.
• If ON and OFF signals are simultaneously given to the ACB, the ON signal is ignored.
Opening the ACB
For opening the ACB remotely, specify the shunt trip device (See P. 23) or the undervoltage trip (See P. 24).

Step-down transformer (external)
The maximum rated control voltage applicable to
the operation power supply is AC240V. For higher
voltages, a step-down transformer is needed.
The following step-down transformers are available
as options.
