Through terminal block, 2052 Series, gray This through terminal block (item number 2052-321) is designed for simple and secure connections. Ensure that the strip lengths are between 10 and 12 mm when connecting conductors to this through terminal block. Whether for industrial or building applications, you can use our through terminal blocks to connect electrical conductors quickly and safely. We offer variants for both classic through-wiring and potential distribution. This product incorporates conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® technology provides a universal connection solution for all conductor types. It allows both solid and fine-stranded conductors with ferrules to be inserted directly into the clamping point without the need for tools. Depending on the type of conductor, this through terminal block is designed 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 different industrial applications and modern building installations. They also offer the perfect solution for every use: lever, push-button, or operating slot. This product is designed for specific Ex applications (please refer to the product datasheet).
