Wieland Electric Introduces selos® NEW GENERATION – New Portfolio of DIN-Rail Terminal Blocks
March 18, 2026
Wieland Electric announces the launch of the selos® NEW GENERATION series, a new line of compact push-in and screw terminal blocks designed to deliver higher performance through space savings, reduced installation and maintenance costs, and improved engineering workflows. As part of the launch, Wieland has introduced digital tools such as selosPLAN for DIN rail assembly design and expanded product data on the ePLAN Data Portal to streamline design and planning. In addition, new modern marking systems support both thermal transfer printing from continuous reels and laser printing for marker cards, ensuring clear and accurate identification for every installation.
The WTPN Series features push-in spring pressure technology, enabling fast, tool-free wiring. Solid and ferruled conductors push in directly, while stranded wires can be inserted using an integrated push button, ensuring secure, vibration-resistant connections regardless of operator experience. Additional features such as push-in jumpers, integrated test points, and snap-on ground terminals, further reduce installation time and improve reliability. With UL and CSA approvals up to 82 A and a wire range of 26–4 AWG, the WTPN Series offers a complete solution for motor, sensor, pluggable, diode, fuse, and test terminal applications.
The WTN Series modernizes the proven screw connection with enhanced reliability and faster installation. Key features include a universal screw head (flat or Phillips), vibration-resistant clamping, snap-on ground terminals, and push-in jumpers. With UL and CSA approvals up to 380 A and a wire range from 26 AWG to 500 kcmil, the WTN Series is a robust solution for demanding industrial applications.
