Three-phase integrated ring main unit circuit breaker operating mechanism

◆Energy storage operation:
Check whether the product has been deformed during transportation, install and fix the mechanism on the switch, use a special operating handle to insert into the lower right part of the mechanism, rotate it clockwise (or energize the motor electrically) until a "click" sound is heard, and the energy storage action is completed.
◆Closing operation:
Turn the green knob, and the main circuit of the circuit breaker switch is closed under the action of the spring force of the mechanism. Or during electric operation, the closing coil is energized and the mechanism is fully closed, and the opening spring is charged at the same time. At this time, the energy can be stored again but the cooperative operation (with interlocking) is no longer possible.
◆Opening operation:
Turn the red knob, and the main circuit of the circuit breaker switch opens under the action of the spring force of the mechanism. Or during electric operation, the opening coil is energized and the mechanism is fully opened.
