2-conductor/1-pin carrier terminal block, 2020 Series, operating tool 2-conductor/1-pin carrier terminal block (item number 2020-1304) simplifies electrical installations. Conductors can only be connected to 2-conductor/1-pin 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. Featuring conductor terminals along with Push-in CAGE CLAMP®, this product delivers reliable performance. 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. Depending on the type of conductor, 2-conductor/1-pin carrier terminal block is ideal for conductor cross sections ranging from 0.14 mm² to 1.5 mm². This pluggable rail-mount terminal block is operated with an operating tool.
