When your switch cabinet wiring needs to be fast, reliable, and built to last, Wieland’s next-generation SELOS WTN and WTPN series deliver. Here’s what makes them worth specifying.
The right terminal block is foundational to every well-built switch cabinet. At Area51 Electronics, we partner with manufacturers who get that, and Wieland Electric is one we’re proud to stand behind.
With over a century of engineering expertise, Wieland has built a global reputation for connection technology that performs in real-world conditions, not just on data sheets. Their next-generation SELOS DIN rail terminal block lineup, the SELOS WTN (screw connection) and SELOS WTPN (push-in) series, brings two powerful, modernized connection technologies under one unified product family, covering everything from compact automation panels to heavy power distribution.
Two next-generation series WTN screw and WTPN push-in – under one unified SELOS platform for any application.
Simplified terminal strip planning and easy component ordering streamline every project.
Pre-assembled terminal strips enable quick installation and minimize cabinet downtime.
High, sustained contact pressure across all families means no re-tightening — ever.
Wieland’s next-generation SELOS lineup consolidates their DIN rail terminal block offering into two purpose-built series, each engineered around a distinct connection technology, and both backed by UL and CSA approvals for North American installations.
The WTN series takes Wieland’s proven screw connection and brings it fully up to date. A universal screw head (flat or Phillips) means no hunting for the right tool, while vibration-resistant clamping ensures the connection holds in demanding environments. Snap-on ground terminals and push-in jumpers further speed up installation and reduce wiring complexity.
Whether you’re wiring signal circuits or heavy power feeds, the WTN covers an exceptional range, making it the go-to choice for versatile panel builds.
The WTPN series is built for speed without sacrificing reliability. Solid and ferruled conductors push in directly, no tools required. Stranded wire installs just as easily using the integrated push button, ensuring a secure, vibration-resistant connection every time. Integrated test points make circuit verification fast and straightforward without disturbing the connection.
Push-in jumpers and snap-on ground terminals reduce installation time further, making WTPN the ideal choice for high-volume panel builds where every minute counts.
Area51 Electronics is an authorized Wieland distributor with the product knowledge to match the right terminal block to your exact application. Whether you’re speccing a prototype or sourcing for production, our team is ready to help.
