1-conductor/1-pin double-deck carrier terminal block, 2020 Series, operating tool 1-conductor/1-pin double-deck carrier terminal block (item number 2020-2232) provides seamless electrical installations. Ensure that the strip lengths are between 9 and 11 mm when connecting conductors to 1-conductor/1-pin double-deck carrier 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 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® connection technology is ideal for connecting all conductor types. Solid and fine-stranded conductors with ferrules can be inserted without needing to use any tools—all thanks to its pluggable design. 1-conductor/1-pin double-deck carrier terminal block is suitable 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.
