Feedthrough terminal block, 741 Series, with 7.5 mm pin spacing Seamless electrical installations are guaranteed with feedthrough terminal block (item number 741-307). Conductors should only be connected to feedthrough terminal block if their strip length is between 5 and 6 mm . Featuring one conductor terminal along with CAGE CLAMP®, this product is highly versatile. 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 item's dimensions are (51.5 x 22.5 x 12.8) 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. Tin is used for coating the contact surfaces.
