2104-5201 Wago 2-conductor through terminal block;with lever and push-button;4 mm²;gray

Why Choose the WAGO 2104-5201 TOPJOB S 2-Conductor Through Terminal Block?

The WAGO 2104-5201 is a 2-conductor through terminal block with lever and push-button operation from the TOPJOB® S range. Designed for 4 mm²-class wiring, this grey DIN rail terminal combines WAGO spring-clamp technology with intuitive operating elements for efficient conductor termination in industrial control panels, machinery and electrical distribution systems.

The combination of lever and push-button operation provides convenient access to the spring connection during installation, testing, maintenance and rewiring. Suitable conductors can also benefit from direct push-in termination, reducing installation effort while retaining the consistent contact pressure associated with WAGO spring-clamp connections.

The 2104-5201 provides two conductor connection points on one electrical potential for straightforward feed-through wiring. Its compact DIN rail format, grey insulating housing and integrated marking and testing provisions make it a practical choice for clearly organised professional terminal assemblies requiring a 4 mm² nominal cross-section.

Key Advantages

• 4 mm² nominal cross-section for industrial power and control wiring.
• Combines lever and push-button operation for convenient conductor handling.
• Spring-clamp connection maintains consistent contact pressure without routine screw retightening.

Flexible 4 mm² Through-Wiring with Lever and Push-Button Operation

The WAGO 2104-5201 is designed to make conductor termination and subsequent maintenance straightforward. Its spring-clamp connection maintains pressure on the conductor, while the lever and push-button operating elements provide convenient ways to open the connection when inserting, removing or replacing conductors.

Both connection points share the same electrical potential, allowing the terminal to perform a conventional feed-through function between incoming and outgoing conductors. The modular TOPJOB S design also supports organised DIN rail assemblies with appropriate WAGO marking, testing and terminal accessories.

Typical Applications

• Industrial control panel wiring.
• Machine-building and OEM electrical equipment.
• PLC and automation system terminal assemblies.
• Power and control circuit distribution.
• Building electrical and control installations.
• DIN rail assemblies requiring accessible feed-through connections.
