The Wieland Electric WK series modular terminal blocks represent a culmination of decades of experience in terminal block design. Key features include pressure connectors for secure and vibration-resistant connections, rapid mounting tools for efficient installation, and a robust polyamid 6.6 insulating housing. The pressure connectors, made of hardened steel and zinc-plated with chromate, provide high contact pressure, while the current bars, made of copper or brass with tin-lead alloy plating, ensure excellent contact properties. The design minimizes damage to wires, even fine-stranded ones, often eliminating the need for ferrules or wire pins. These terminal blocks are ideal for a wide range of industrial applications requiring reliable and efficient power distribution.
