2-conductor/1-pin carrier terminal block, 2222 Series, push-button Enjoy fault-free electrical installations with 2-conductor/1-pin carrier terminal block (item number 2222-1301). Strip lengths must be between 10 and 12 mm when connecting conductors to 2-conductor/1-pin 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. 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 0.25 mm² to 4 mm². A push-button is used to operate this pluggable rail-mount terminal block.
