Through terminal block, 870 Series, operating tool
This through terminal block (item number 870-685) streamlines wire connections, making them both quick and easy. Ensure that the strip lengths are between 6 and 7 mm when connecting conductors to this through terminal block. Our mini rail-mount terminal blocks are perfect for working in small spaces thanks to their compact design. With various mounting and actuation options, they offer complete flexibility. This product incorporates conductor terminals and utilizes CAGE CLAMP®. Our renowned universal connection known as CAGE CLAMP® is the industry standard when it comes to connection technology and electrical interconnections. This through terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm².
An operating tool is used to operate this mini rail-mount terminal block.
