PCB terminal block, 255 Series, with 7.5 mm pin spacing Our PCB terminal block (item number 255-510/333-000) simplifies electrical installations. It offers the flexibility needed for different mounting types. Conductors can only be connected to this PCB terminal block if their strip length is between 5 and 6 mm . Featuring one conductor terminal along with CAGE CLAMP®, this connector delivers reliable performance. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all conductor types without having to prepare the conductor. For example, you don't need to crimp ferrules. Dimensions: (77.9 x 22.2 x 23) mm (width x height x depth). Depending on the type of conductor, this PCB terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². Tin is used for coating the contact surfaces. This PCB terminal block is operated with finger-operated lever. THT is used to solder the PCB terminal block. The conductor is designed to be inserted at an angle of 90°..
