2-conductor/1-pin carrier terminal block, 2020 Series, gray Enjoy fault-free electrical installations with 2-conductor/1-pin carrier terminal block (item number 2020-1301). Conductors can only be connected to 2-conductor/1-pin 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 features conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® technology provides a universal connection solution for all conductor types. 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 conductor type, 2-conductor/1-pin carrier terminal block is ideal 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.
