Shield terminal block, 281 Series, CAGE CLAMP® Connecting conductors is quick and easy with this shield terminal block (item number 281-658). Strip lengths must be between 9 and 10 mm when connecting conductors to this shield terminal block. Shield terminal blocks connect directly to the mounting rail via an integrated contact foot. This creates an electrical and mechanical connection between the electrical conductors and the mounting adapter and ensures that interference signals are safely dissipated. This product features conductor terminals and utilizes CAGE CLAMP®. Our highly-rated 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. This shield terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm². This through rail-mount terminal block is operated with an operating tool.
