Overview

WILLELE UK terminal block provide secure, maintenance-free connections for industrial control panels and power distribution. Featuring spring-cage clamping for consistent contact force under vibration, the range covers feed-through, high-current, double-level, knife-disconnect, and protective earth (PE) grounding types. Rated up to 1000 V and 309 A depending on model, UK Series blocks mount on standard TS35/TS15 rails and support a broad conductor window from 1.5 mm² to 150 mm². A full accessory ecosystem—markers, end brackets, end clamps, and jumper links—simplifies fast, tidy panel assembly.

Key Features

Spring-cage clamp: stable, vibration-resistant connections; no periodic re-tightening
Wide electrical range: up to 1000 V and 309 A (model-dependent)
Form factors: single feed-through, high-current (UKH), double-level (UDK), knife-disconnect (DREHSI), and PE ground (USLKG)
Fast installation: snap on TS35/TS15 rails; color-coded options for quick circuit ID
Accessories: marker strips, end brackets, end clamps, jumper links for group wiring
Compliance-ready: designed for IEC/EN control panel standards (e.g., IEC 60947)

FAQ

Which rail types are supported?

UK terminal block series mounts to standard DIN rails (TS35/TS15). Check individual model width and accessories for fit.

Do I need to re-tighten connections?

No. Spring-cage clamps maintain contact force without periodic re-tightening, reducing maintenance.

How do I choose the correct model?

Match conductor size, current, and voltage. For PE grounding use USLKG models; for high current select UKH; for compact wiring choose UDK double-level.

What accessories are available?

Marker strips (MB4–MB12), end brackets (E/UK-2, E/UK-3), and end clamps (FEW-3S, FB1, FB2, FB3), plus jumper links for group wiring.
