Through DIN rail connector WDU 4 1020100000

Universal busbar connector for safe and efficient wire connection

The WDU 4 through busbar connector is a reliable solution for connecting wires in electrical installations. Designed for durability and ease of installation, it performs well in both industrial and building installations. Its construction allows for safe and organized routing of wires from the busbar, minimizing the risk of short circuits and failures.

Construction and application

Made of high-quality thermoplastic material with flammability class V0, it provides resistance to high temperatures and fire. Mounting is done on a standard DIN TH-35 mm rail, which simplifies integration with existing systems. The connector accepts both solid and stranded wires (with or without ferrules) with a cross-section from 0.5 mm² to 6 mm², providing great flexibility in wire selection. Thanks to screw connections, it guarantees a secure and durable electrical connection. A required cover plate provides additional safety and aesthetics of the installation.

Key features and benefits

• Wide range of wire cross-sections: Support for wires from 0.5 mm² to 6 mm² – both solid and stranded – increases versatility of application.
• Safety: Insulation material with flammability class V0 minimizes the risk of fire spreading in the event of a failure.
• Durability: Made of high-quality thermoplastic material ensures resistance to environmental conditions and long-term use.
• Easy installation: Standard mounting on a DIN TH-35 mm rail simplifies installation and integration with existing systems.
• Explosion-proof design: Ex-e certificate confirms the possibility of use in potentially explosive areas (detailed information in the technical documentation).
• Suitable for working in harsh conditions: Operating temperature range from -60°C to 130°C allows for use in demanding industrial environments.
• Reliable connection: Screw connections ensure a stable and secure electrical connection, minimizing the risk of loosening over time.
• Load resistance: Rated current of 32A and rated voltage of 800V allow for safe operation in circuits with high load.
