PCB terminal block, 255 Series, gray Our PCB terminal block (item number 255-524/333-000) simplifies electrical installations. You can count on trusted safety with these PCB terminal blocks, perfect for a host of applications when designing your devices. Conductors should 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 outperforms the competition. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don't need to crimp ferrules. The dimensions are (182.9 x 22.2 x 23) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is designed for conductor cross sections ranging from 0.08 mm² to 2.5 mm². The contact surface is coated with tin. This PCB terminal block is operated with finger-operated lever. The PCB terminal block is designed for THT soldering. The conductor is designed to be inserted at an angle of 90°..
