What is the Wago 2052-321?

Through terminal block, 2052 Series, Push-in CAGE CLAMP®

Our through terminal block (item number 2052-321) ensures effortless electrical installations. Strip lengths must be between 10 and 12 mm when connecting conductors to this through terminal block. Whether for use in industry or building installations, our rail-mount through terminal blocks allow you to quickly and securely connect electrical conductors. They’re perfect for either classic through-wiring or distributing potential, depending on the variant. This product incorporates conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. Solid and fine-stranded conductors with ferrules can be pushed in without needing to use any tools—all thanks to its pluggable design. This through terminal block is suitable for conductor cross sections ranging from 0.25 mm² to 4 mm².

An operating tool is used to operate this mini rail-mount terminal block. Our TOPJOB® S rail-mount terminal blocks offer more than just secure electrical connections in all kinds of industrial applications and modern building installations. They also offer the perfect actuation option for every need: lever, push-button, or operating slot. This product is designed for specific Ex applications (please refer to the product datasheet).
