2-conductor/2-pin carrier terminal block, 2020 Series, operating tool 2-conductor/2-pin carrier terminal block (item number 2020-1401) provides fault-free electrical installations. Conductors can only be connected to 2-conductor/2-pin carrier terminal block if their strip length is between 9 and 11 mm . Pluggable rail-mount terminal blocks are primarily found in switchgear units and control systems, most notably in railroad technology. These innovative systems combine the properties 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. This product incorporates conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® technology provides a universal connection solution for any type of conductor. It allows both solid and fine-stranded conductors with ferrules to be inserted directly into the clamping point without the need for tools. Depending on the type of conductor, 2-conductor/2-pin carrier terminal block is ideal for conductor cross sections ranging from 0.14 mm² to 1.5 mm². An operating tool is used to operate this pluggable rail-mount terminal block.
