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.
