1-conductor/1-pin double-deck carrier terminal block, 2022 Series, gray Error-free electrical installations are guaranteed with 1-conductor/1-pin double-deck carrier terminal block (item number 2022-2203/999-953). Conductors should only be connected to 1-conductor/1-pin double-deck carrier terminal block if their strip length is between 10 and 12 mm . Pluggable rail-mount terminal blocks are mainly used in switchgear units and control systems (e.g., in railroad technology). They are essentially a combination of rail-mount terminal blocks and pluggable connectors. You can also pre-assemble installations thanks to the variable wiring system. This saves both time and money during manufacture, 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. 1-conductor/1-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. This product is designed for specific Ex applications (please refer to the product datasheet).
