1-conductor/1-pin double-deck carrier terminal block, 2020 Series, operating tool 1-conductor/1-pin double-deck carrier terminal block (item number 2020-2231) simplifies electrical installations. Strip lengths must be 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 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. Featuring conductor terminals along with Push-in CAGE CLAMP®, this product outperforms the competition. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, offering a key advantage: both solid and fine-stranded conductors with ferrules can be directly inserted without the need for tools or any preparation, such as crimping the ferrule. Depending on the conductor type, 1-conductor/1-pin double-deck carrier terminal block is designed for conductor cross sections ranging from 0.14 mm² to 1.5 mm². This pluggable rail-mount terminal block is operated with an operating tool.
