Female connector, 2020 Series, operating tool This female connector (item number 2020-204/143-000) simplifies electrical installations. Strip lengths must be between 9 and 11 mm when connecting conductors to this female connector. 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® technology provides a universal connection solution for all conductor types. It allows both solid and fine-stranded conductors with ferrules to be inserted directly into the clamping point without the need for tools. Dimensions: (14.7 x 59 x 29.8) mm (width x height x depth). Depending on the conductor type, this female connector is designed for conductor cross sections ranging from 0.14 mm² to 1.5 mm². This female connector/socket is operated with an operating tool. The strain relief plate is a safety precaution for connected conductors that also makes wires easier to handle..
