The present invention provides a stack-structure modular power connection device which includes: a main circuit breaker and a plurality of branch circuit breakers which are installed on an installation panel or installation board; and one or more sub bus bar connection units which electrically connect the main circuit breaker and the branch circuit breakers to distribute power supplied from the outside. The sub bus bar connection units are connected to a main bus bar which guides power by being connected to the output terminal of the main circuit breaker and supplies power distributed from the main bus bar to each branch circuit breaker. Each of the sub bus bar connection units includes: a connection block which is fixed by a coupling unit penetrating through a coupling hole onto a panel of a distribution board; a first sub bus bar of which one end is accommodated in the valley of the connection block and the other end is connected to the main bus bar by a clip; a second sub bus bar of which the central part is stacked onto the top of the end of the first sub bus bar and one end is connected to the branch circuit breakers; and a third sub bus bar which is electrically connected to the first and the second sub bus bar and is stacked and extended using a coupling unit to allow another circuit breaker to be connected on the other side. |
