1-conductor/1-pin double-deck carrier terminal block, 2022 Series, gray Enjoy convenient electrical installations with 1-conductor/1-pin double-deck carrier terminal block (item number 2022-2227). Conductors should only be connected to 1-conductor/1-pin double-deck carrier terminal block if their strip length is between 10 and 12 mm . Pluggable rail-mount terminal blocks are primarily found in switchgear units and control systems, most notably in railroad technology. These innovative systems combine the properties of rail-mount terminal blocks and connectors for a flexible and reliable wiring system. You also have the option of pre-assembling installations, which not only makes production but also installation, operation, and maintenance more efficient and cost-effective. Featuring conductor terminals along with Push-in CAGE CLAMP®, this connector delivers reliable performance. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. It allows direct insertion of both solid and fine-stranded conductors with ferrules without needing to use any tools—all thanks to its pluggable design. 1-conductor/1-pin double-deck carrier terminal block is suitable for conductor cross sections ranging from 0.25 mm² to 4 mm². This pluggable rail-mount terminal block is operated with an operating tool.
