Component terminal block with diode, 769 Series, operating tool Connecting conductors is quick and easy with this component terminal block with diode (item number 769-218/281-411). Conductors should only be connected to this component terminal block with diode if their strip length is between 8 and 9 mm . 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 CAGE CLAMP®. Our proven universal connection known as CAGE CLAMP® is the industry standard when it comes to connection technology and electrical interconnections. Depending on the conductor type, this component terminal block with diode is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm². This pluggable rail-mount terminal block is operated with an operating tool.
