2-conductor/2-pin double-deck carrier terminal block, 2022 Series, operating tool 2-conductor/2-pin double-deck carrier terminal block (item number 2022-2237) is designed for seamless electrical installations. Conductors can only be connected to 2-conductor/2-pin double-deck carrier terminal block if their strip length is between 10 and 12 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 for 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 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 double-deck carrier terminal block is suitable for conductor cross sections ranging from 0.25 mm² to 4 mm². This pluggable rail-mount terminal block is operated with an operating tool.
