Ukk Junction Box Naming Rules Explained: How To Quickly Identify The Model Based On Rated Current
Selecting the right industrial component requires precision. A UKK splitter box manages electrical currents safely, but identifying the exact specifications from a model number can be challenging. This guide provides a straightforward breakdown of standard naming conventions, helping technical teams instantly recognize critical technical ratings.
How to Decode a UKK Splitter Box Part Number
Manufacturers utilize specific alphanumeric codes to describe the internal configuration and capacity of din rail power distribution terminal blocks. The initial letters denote the series, while the subsequent digits typically pinpoint the exact amperage rating and terminal count.
Identifying the Amperage Rating
The most critical number in the sequence represents the maximum current capacity. For example, in a UKK 80A model, the digits explicitly state the rated current of 80 amperes. Larger systems require higher capacities, which are reflected directly in names like UKK 125A or UKK 250A.
Terminals and Pole Configurations
Beyond current ratings, numbers also indicate the layout of a din distribution block. A standard configuration includes one main input terminal and multiple smaller output ports, ensuring efficient energy routing across industrial control panels.
Model Selection Matrix by Electrical Load
The following table summarizes common configurations for low to medium voltage applications, matching model names with their specific electrical limits:
| Model Designation | Rated Current (Amps) | Input Terminals | Output Terminals |
|---|---|---|---|
| UKK 80A | 80A | 1 x 16 mm² | 2 x 16 mm² / 4 x 10 mm² |
| UKK 125A | 125A | 1 x 35 mm² | 2 x 16 mm² / 5 x 10 mm² |
| UKK 160A | 160A | 1 x 70 mm² | 6 x 16 mm² |
| UKK 250A | 250A | 1 x 120 mm² | 2 x 35 mm² / 5 x 16 mm² / 4 x 10 mm² |
Alternative Solutions for Complex Distribution
When simple single-pole configurations are insufficient, multi-phase systems become necessary. For three-phase setups, a 4 pole power distribution block offers a centralized solution. These compact units combine multiple din rail power distribution terminal blocks into a single housing, streamlining wire management. Utilizing a power distribution block 4 pole design saves valuable enclosure space while maintaining clear phase separation for complex machinery.
