a shutter plate disposed to cover an external terminal disposed on a rear surface of a switchboard case; and
a shutter driving unit connected to one side of the shutter plate and configured to move the shutter plate in a left-right direction, including:
a bracket mounted on a side plate of the switchboard case that includes a bracket body mounted on a side surface of the switchboard case, and wherein the bracket body includes:
an elastic member hook protrusion protruding from a first end of the bracket body and configured to fix a first end of an elastic member; and
a coupling protrusion protruding from a second end of the bracket body opposite to the first end of the bracket body and protruding in a direction opposite to a protruding direction of the elastic member hook protrusion;
a slider connected to the bracket to be moved relative to the bracket;
a main body disposed close to a front surface of the switchboard case; and
a first split body and a second split body vertically separated and extending from the main body toward the rear surface of the switchboard case,
wherein:
when the slider is moved toward the rear surface or the front surface of the switchboard case by a circuit breaker, the slider moves at least a portion of the shutter plate
the shutter driving unit is configured so that the shutter plate is moved by at least a portion that is rotated by being pressed by the circuit breaker as the circuit breaker enters the switchboard case so that the external terminal covered by the shutter plate is exposed toward an inside of a switchboard.
