1-conductor/1-pin carrier terminal block, 2222 Series, push-button 1-conductor/1-pin carrier terminal block (item number 2222-1204) provides seamless electrical installations. Strip lengths must be between 10 and 12 mm when connecting conductors to 1-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. This product features conductor terminals and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. Solid and fine-stranded conductors with ferrules can be inserted without needing to use any tools—all thanks to its pluggable design. Depending on the type of conductor, 1-conductor/1-pin carrier terminal block is designed 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.
