The Number Of Output Poles For A Ukk Junction Box Depends On The Power System Configuration.

The number of output poles for the single pole distribution block is not arbitrarily set, but is closely linked to the power supply system configuration. Different power supply system structures determine the number of branches required in the circuit and the current capacity of each output loop, thus affecting the number and configuration of the modular distribution block's output terminals.

The terminal block 250a is used as a distribution node in power wiring, and its design generally employs a "one-in, multiple-out" terminal structure. This structure allows the main power supply line to be connected through a single input terminal and then distributed to multiple output ports to support different branches. The setting of the number of output poles is closely related to the single-phase or three-phase structure of the power supply system, the current rating, and the load distribution. For example, in a single-phase system, fewer output terminals may be needed to support branch circuits, while in a three-phase system, more output terminals are required to accommodate more parallel connections in order to lead out three phase lines and a neutral line.
