Description
Through terminal block, 781 Series, light grayOur through terminal block (item number 781-993) ensures effortless electrical installations. Conductors should only be connected to this through terminal block if their strip length is between 9 and 10 mm . This product incorporates conductor terminals and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection provides a reliable 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. Depending on the type of conductor, this through terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 4 mm².
