Overview

YOCL ELECTRIC UK Series Screw DIN Rail Terminal Blocks provide conductor connections and circuit organization in electrical panels, control cabinets and DIN rail assemblies. The series uses a screw-clamp connection with a PA66 nylon insulating housing and brass conductive components.

The range includes standard feed-through, compact, multi-level, twin-connection, disconnect and special-function configurations, plus yellow-green USLKG protective-earth terminals. Current and voltage ratings, dimensions, stripping lengths and screw sizes vary by model. Rigid and flexible conductor ranges are listed for selected models below.

Features

Screw-clamp connections: Conductors are secured by the terminal screw.
DIN rail mounting: Individual terminals can be arranged side by side in a terminal assembly.
PA66 nylon housing and brass components: Insulating housings and conductive components use the listed materials.
Multiple configurations: Standard, compact, multi-level and other configurations support different circuit layouts.
Protective-earth models: Yellow-green USLKG terminals are available for PE connections.
Jumper and end plate options: Model-specific accessories support potential distribution and terminal assembly.

Selection Guide

Select the terminal configuration, then check the current rating, voltage rating, dimensions, stripping length and screw size for that exact model. For example, UK-240N is rated 415 A at 1000 V, while UK-10RD is rated 10 A at 800 V. These ratings belong to the individual models.

Use the stated rigid or flexible conductor range where provided. Conductor capacity cannot be determined from the model name alone. For USLKG-35, the listed ranges are 0.75–50 mm² for rigid conductors and 0.75–30 mm² for flexible conductors.

Standard terminal models are predominantly grey. Select color by model; yellow-green is specified for the USLKG protective-earth range.

Jumpers, End Plates and Enclosed Housings

Multiple models support center-type jumpers for potential distribution between adjacent terminals. Jumper examples include FB1, EB1 and EBL, alongside model-specific configurations. Match the jumper to the selected terminal model.

End plates are specified for applicable terminal sizes. The following models have enclosed housings and require no separate end plates:

UK-35N
UIK-35N
UK-50N
UK-95N
UK-150N
UK-240N

Specify any required jumper, end plate or other accessory with the terminal model it will be used with.
