2-conductor/1-pin double-deck carrier terminal block, 2020 Series, operating tool Our 2-conductor/1-pin double-deck carrier terminal block (item number 2020-2239) ensures effortless electrical installations. Strip lengths must be between 9 and 11 mm when connecting conductors to 2-conductor/1-pin double-deck 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: 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, 2-conductor/1-pin double-deck carrier terminal block is suitable 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.
