New Terminal Blocks from Wieland Electric
February 5, 2026
Optimized for Practical Use and Built for the Future
As the inventor of secure electrical connection technology in 1910, Wieland Electric has been a reliable partner for industry and buildings for over a century. With the new ‘selos NEW GENERATION’ terminal block series, Wieland is now launching a forward-looking portfolio that meets the increasing demands of switch cabinet construction. The new generation combines proven technologies with innovative solutions and offers a comprehensive system of terminal blocks, matching accessories, digital services and printing solutions.
Easy handling for maximum efficiency in switch cabinet construction
The new selos WTPN terminal blocks with push-in technology enable fast, tool-free wiring for rigid conductors and conductors with ferrules, and offer a vibration-proof, maintenance-free connection with high contact force. The selos WTN terminal blocks with screw connection impress with maximum conductor compatibility and robust cage clamp technology, making them ideal for demanding industrial applications.
The uniform accessory system for both connection types reduces complexity and storage requirements. Thanks to space-saving multi-level terminals and a size reduction of up to 66%, control cabinet projects can be implemented more efficiently. This is a real advantage in view of rising labour costs and the shortage of skilled workers.
Digitally supported and easy to implement
With the selosPLAN planning tool, EPLAN data and preconfigured terminal strips, Wieland offers a comprehensive solution for project planning, documentation and labelling. Integration into existing processes enables error-free workflows and saves time and money.
Technology you can trust
For over 100 years, Wieland has been synonymous with reliable connection technology. The new series impresses with its durable, maintenance-free components, immediate availability of all parts and accessories from stock, and global certifications. All this together guarantees investment security and minimises downtime.
Sustainable and future-proof
selos NEW GENERATION already meets the requirements of the revised RoHS Directive 2027 and uses lead-free materials. With stable prices, centralised warehousing and long-term technical documentation, Wieland offers global supply security and predictability.
