1-conductor/1-pin double-deck carrier terminal block, 2020 Series, operating tool Our 1-conductor/1-pin double-deck carrier terminal block (item number 2020-2217) is designed for seamless electrical installations. Conductors should only be connected to 1-conductor/1-pin double-deck carrier terminal block if their strip length is between 9 and 11 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 incorporates conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. Both solid and fine-stranded conductors with ferrules can be plugged in without the need for tools—all thanks to its pluggable design. 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.
