Page Content

WKH distribution boxes are modular power distribution terminal blocks designed for compact, safe, and flexible electrical connections in panels and machinery.

Overview

WKH distribution boxes, also known as WKH power distribution terminal blocks, are used to distribute electrical power and establish connections between wires of different cross-sections. They are commonly applied in installation and distribution boards, mechanical controllers, and machinery control panels . These blocks allow for single or multiple pole configurations in a compact footprint, enabling high-density panel construction .

Design and Features

  • Mounting Options: WKH blocks can be snapped onto NS 35 DIN rails or screwed directly onto mounting plates using side flanges .
  • Safety: Many models include hinged or removable covers to prevent accidental contact with energized connectors and reduce the risk of short circuits .
  • Compact and Efficient: The design allows for smaller panels while maintaining high conductor density, saving installation space .
  • Electrical Capacity: Depending on the model, WKH blocks can handle voltages up to 500V and currents up to 125A, with conductor sizes up to 35mm² .
  • Compliance: Products are often CE marked, RoHS compliant, and tested for high conductivity and reliable electrical contact .

Variants

  • WKH-207: Unipolar distribution box for 500V, 125A applications .
  • WKH-211: Modular junction box with 2 x 11 pins for DIN rail mounting .
  • WKH-411: Junction box with 4 x 11 holes, suitable for multiple conductors and customizable wiring configurations .

Applications

  • Electrical distribution in industrial panels
  • Machinery control systems
  • Compact electrical installations requiring high-density wiring
  • Safe splicing and tap-off points for secondary circuits WKH distribution boxes provide a versatile, safe, and space-efficient solution for electrical distribution, suitable for both industrial and commercial applications. They are widely available from manufacturers in China and can be customized for specific installation needs .
