Description
Through terminal block, 283 Series, redThis through terminal block (item number 283-903) streamlines wire connections, making them both quick and easy. Conductors should only be connected to this through terminal block if their strip length is between 16 and 17 mm . Whether for industrial or building applications, you can use our through terminal blocks to connect electrical conductors quickly and safely. We offer variants for both classic through-wiring and potential distribution. This product features conductor terminals and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection provides a safe 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 0.2 mm² to 16 mm².This through rail-mount terminal block is operated with an operating tool.
