Through terminal block, 279 Series, gray
This through terminal block (item number 279-621) streamlines wire connections, making them both quick and easy. Conductors can only be connected to this through terminal block if their strip length is between 8 and 9 mm . Whether in industrial or building applications, our rail-mount through terminal blocks are the perfect solution to quickly and securely connect electrical conductors. Depending on the version, you can use them for either typical through-wiring or potential distribution. This product features conductor terminals and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection provides a secure and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. Depending on the conductor type, this through terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 1.5 mm².
This through rail-mount terminal block is operated with an operating tool.
