In High-capacity Ukk Junction Boxes, Ukk Only Handles The Phase Wires.

In the high-capacity din rail power distribution wiring arrangement, the UKK only handles the distribution of phase connections. Its structure is based on a single-terminal design, distributing a single input phase line to multiple output ports via internal copper alloy conductors, allowing each output circuit to directly draw power.

This single-phase distribution in a high-current system has a clear logic: the one-in-many-out layout designed inside the din rail power distribution block allows the main power supply phase line to enter the 4 pole distribution block box at the input end and be transmitted to each branch circuit through the terminal block. Different UKK models adjust the number and arrangement of terminals according to the number of output lines, ensuring that each output branch can be connected according to its designed current-carrying capacity.
