The DC switch/AC circuit breakers can be used together with a micro-motor.
When there is the power supply on the AC side of the inverter, the energy can
be stored to the breaker through this motor. When there is no power supply on
the AC side of the inverter, manually store the energy through the manual
energy storage handle.
The operation steps are briefly described by taking the DC switch as an example.
