1-conductor/1-pin ground carrier terminal block, 2020 Series, operating tool 1-conductor/1-pin ground carrier terminal block (item number 2020-1207) simplifies electrical installations. Conductors can only be connected to 1-conductor/1-pin ground 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 features 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: both solid and fine-stranded conductors with ferrules can be directly inserted without the need for tools or any preparation, such as crimping the ferrule. 1-conductor/1-pin ground carrier terminal block is suitable 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.
