Feedthrough terminal block, 231 Series, gray Our feedthrough terminal block (item number 231-611/023-000) simplifies electrical installations. Strip lengths must be between 8 and 9 mm when connecting conductors to feedthrough terminal block. Featuring one conductor terminal along with CAGE CLAMP®, this connector delivers reliable performance. Our CAGE CLAMP® connection provides a secure and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. The item's dimensions are (70.2 x 19 x 19.1) mm (width x height x depth). Depending on the conductor type, feedthrough terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². The contact surface is coated with tin. The feedthrough terminal block is designed for THT soldering.
