1-conductor/1-pin double-deck carrier terminal block, 2020 Series, operating tool Effortless electrical installations are guaranteed with 1-conductor/1-pin double-deck carrier terminal block (item number 2020-2234). Conductors should only be connected to 1-conductor/1-pin double-deck carrier terminal block if their strip length is between 9 and 11 mm . Pluggable rail-mount terminal blocks are hugely popular in switchgear and control systems, for example, in railroad technology. They combine the best of rail-mount terminal blocks and connectors to create the perfect solution. Variable wiring systems make pre-assembly easy, which saves both time and money in production, installation, operation, and maintenance. This product incorporates conductor terminals and utilizes Push-in CAGE CLAMP®. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, boasting a key feature: 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. 1-conductor/1-pin double-deck carrier terminal block is suitable 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.
