Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this shield terminal block. Shield terminal blocks connect directly to the mounting rail thanks to a built-in contact foot. This creates an electrical and mechanical connection between the electrical conductors and the mounting adapter, and safely dissipates interference signals. This product features conductor terminals and utilizes CAGE CLAMP®. Our celebrated universal connection known as CAGE CLAMP® is industry-leading when it comes to connection technology and electrical interconnections. Depending on the conductor type, this shield terminal block is designed for conductor cross sections ranging from 0.08 mm² to 2.5 mm².
