(Note) In consideration of the voltage drop, set the power supply capacity for the solenoid not to be less than the operating voltage.

10.2 Direct switching operation

10.2.1 Closing
When the voltage for the ON operation is applied to A1 and A2 of the control circuit terminal block and the
ON button on the circuit breaker is pushed, the circuit breaker is closed and "ON" is displayed on the ON/OFF
indicator. The operating load is 50 N or less. The circuit breaker has the one-pulse circuit that operates only
once with one closing instruction.
For the circuit breaker with the Under voltage trip device (UVT), when the power supply is applied to D1 and
D2 terminals, the circuit breaker is closed. (The circuit breaker can be closed 1.5 seconds after the power
supply is applied to the Under voltage trip device (UVT).)
(Note)
If the voltage for the ON operation is not applied to A1 and A2 of the control circuit terminal block, the
circuit breaker is not closed even if the ON button is pushed. If the OFF lock devices (padlock, cylinder
lock, or castell lock) are used, perform the closing operation after releasing the lock. For the drawout
type, open/close the circuit breaker when the drawout position is CONNECT or TEST and the lock plate
protrudes. For the circuit breaker with the Under voltage trip device (UVT), apply the rated voltage to
the circuit breaker.
a. Failure to do so can result in the circuit breaker closed (turned ON) accidentally due to malfunction of
the control circuit (or switches) connected to S1 and S2 .
b. The control circuit to close the circuit breaker is comprised of the semiconductor elements. If the surge
or noise more than the specified value is applied to the circuit breaker, the circuit can be damaged.
c. The safety circuit is built in to prevent accidental operation when the circuit breaker is damaged. To
reduce the risk, do not apply the power supply to A1 and A2 when the circuit breaker is not closed
for a long term.
10.2.2 Opening
When the OFF button is pushed, the circuit breaker is opened and "OFF" is displayed on the ON/OFF indicator.
The operation load is 50 N or less.
