DIN rail through connector WDU 35 1020500000

Busbar connector through – reliable connection in the installation

The WDU 35 through busbar connector is a component dedicated to safe and efficient connection of conductors in electrical systems. It will work both in industrial installations and in power distribution boards, ensuring a stable connection and high reliability. The construction based on proven screw technology guarantees a secure fastening of conductors with a cross-section of up to 35 mm², and high-quality materials ensure long-term operation.

Construction and application

The connector is designed for mounting on a standard DIN TH-35 mm rail. Its beige color facilitates identification in the installation, and compact dimensions allow for optimal use of space inside the distribution board. Thanks to two terminals on one level, it allows connecting two conductors simultaneously. Made of thermoplastic (Wemid), it is characterized by high resistance to mechanical damage and external factors, and the flammability class V0 provides additional safety in the event of a fire. The connector requires a closing plate for full functionality and connection safety.

Key features and benefits

• Wide range of conductor cross-sections: Support for solid conductors (2.5 - 16 mm²), stranded conductors with ferrules (2.5 - 35 mm²) and multi-strand conductors (2.5 - 50 mm²) provides flexibility when selecting appropriate cables.
• High resistance to environmental conditions: Operating temperature range from -60°C to 130°C allows the connector to be used in harsh industrial conditions.
• Safety confirmed by standards: Compliance with IEC 60947-7-1 standard and flammability class V0 according to UL94 guarantee a high level of safety.
• Durable construction: Wemid insulating material provides resistance to mechanical and chemical damage, which translates into a long product life.
• Rated current 125A: Allows safe transmission of large currents, which is important in demanding industrial applications.
• Ex-e explosion-proof design: Confirmed Ex-e explosion-proof design increases safety in potentially hazardous environments.
• Easy installation: Quick and easy installation on a standard DIN TH-35 mm rail saves installers time.
