    • A power distribution apparatus is provided. The apparatus may include a modulated block type power distribution apparatus capable of reducing a space by consequently connecting a main breaker to a sub breaker as a block not to form a gap while installing. The apparatus may include a multifunctional block type power distribution apparatus capable of easily connecting breakers with one another, the breaker having different height, by additionally installing a height controller able to control a height of a branch breaker on the apparatus manufactured in one mold and preventing wrong coupling while connecting a plurality of branch breakers with one another. The apparatus may include a preassembled power distribution apparatus capable of increasing coherence between terminals while coupling a main breaker terminal, a branch breaker terminal, and an additional breaker terminal, forming the preassembled power distribution apparatus, with various terminals of another preassembled power distribution apparatus.
    • 提供配电装置。 该装置可以包括调制块型配电装置,其能够通过在安装时将主断路器连接到不具有间隙的块的副断路器来减小空间。 该装置可以包括一种多功能块式配电装置,其能够容易地将断路器彼此连接,该断路器具有不同的高度,另外安装一个高度控制器,该高度控制器能够控制在一个模具中制造的设备上的分支断路器的高度,并防止 在将多个分支断路器彼此连接时错误耦合。 该装置可以包括预先组装的配电装置,其能够在与另一个预组装的配电装置的各种端子耦合形成预组装的配电装置的主断路器端子,分支断路器端子和附加断路器端子的同时增加端子之间的相干性。
