1-conductor/1-pin double-deck carrier terminal block, 2020 Series, Push-in CAGE CLAMP® 1-conductor/1-pin double-deck carrier terminal block (item number 2020-2257) is designed for hassle-free electrical installations. Strip lengths must be between 9 and 11 mm when connecting conductors to 1-conductor/1-pin double-deck carrier terminal block. 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. Featuring conductor terminals along with Push-in CAGE CLAMP®, this connector delivers reliable performance. 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 type of conductor, 1-conductor/1-pin double-deck carrier terminal block is ideal for conductor cross sections ranging from 0.14 mm² to 1.5 mm². An operating tool is used to operate this pluggable rail-mount terminal block.
