Through busbar connector WDU 4 BL 1020180000

Rail connector through – a reliable connection in the installation

The WDU 4 BL rail connector from Weidmüller is an element used to connect wires in electrical installations. Designed for mounting on a standard DIN TH-35 mm rail, it provides a solid and safe connection for both installers and end users. Its construction allows for easy assembly and disassembly, which facilitates service work and installation modifications.

Construction and parameters for demanding applications

The WDU 4 BL connector is designed for a wide range of applications. It accepts stranded wires with a cross-section from 0.5 to 4 mm² and solid wires up to 6 mm², as well as multi-strand wires from 1.5 to 6 mm². Made of high-quality thermoplastic material, it is characterized by good resistance to external factors and provides electrical insulation. The blue color makes it easier to identify in the installation. An important aspect is also the high flammability class of the insulating material (V0), which increases safety.

The connector uses a screw connection, which guarantees a secure and durable connection of the wires. The rated current of 32A and the rated voltage of 800V allow for use in medium and high power circuits. The operating temperature range from -60°C to +130°C enables operation in harsh environmental conditions. Additionally, the connector has a confirmed explosion-proof design Ex-e, which expands the scope of its applications to areas at risk of explosion. Remember to use a closing plate for full functionality and safety.
