1-conductor/1-pin carrier terminal block, 2222 Series, Push-in CAGE CLAMP® Our 1-conductor/1-pin carrier terminal block (item number 2222-1202/999-953) simplifies electrical installations. Ensure that the strip lengths are 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®. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, boasting a key feature: It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing tools. No preparation is required; for example, crimping the conductor's ferrule is not necessary. Depending on the conductor type, 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. This product is designed for specific Ex applications (please refer to the product datasheet).
