2-conductor/2-pin double-deck carrier terminal block, 2022 Series, blue Our 2-conductor/2-pin double-deck carrier terminal block (item number 2022-2239) ensures effortless electrical installations. Conductors should 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 leads to considerable time and cost savings 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: It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing tools. No preparation is required; for example, crimping the conductor's ferrule is not necessary. 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. An operating tool is used to operate this pluggable rail-mount terminal block.
