Double-deck terminal block, 870 Series, CAGE CLAMP® Easy electrical installations are guaranteed with this double-deck terminal block (item number 870-109). Ensure that the strip lengths are between 6 and 7 mm when connecting conductors to this double-deck terminal block. Pluggable rail-mount terminal blocks are primarily found in switchgear units and control systems, most notably in railroad technology. These innovative systems combine the benefits of rail-mount terminal blocks and connectors for a flexible and reliable wiring system. You also have the option of pre-assembling installations, which not only makes production but also installation, operation, and maintenance more efficient and cost-effective. The double-deck terminal block also serves as a through terminal block. Featuring conductor terminals along with CAGE CLAMP®, this connector outperforms the competition. Our celebrated universal connection known as CAGE CLAMP® is industry-leading when it comes to connection technology and electrical interconnections. Depending on the type of conductor, this double-deck terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². An operating tool is used to operate this pluggable rail-mount terminal block.
