Male connector, 769 Series, gray Our male connector (item number 769-603/001-000) simplifies electrical installations. Conductors should only be connected to this male connector 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 reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don't need to crimp ferrules. This male connector is suitable for conductor cross sections ranging from 0.08 mm² to 4 mm². This male connector/plug is operated with an operating tool.
