If you need a terminal block for your electrical wiring that's compatible with industry-standard fittings, use this RS PRO screw clamp terminal. It fits DIN rails, so you can use it with your existing set-up to extend or upgrade your current electrical system.


This terminal block is easy to install. Simply snap it into place on a standard DIN rail. The screw clamp keeps terminated wires fixed securely in place and requires only a standard screwdriver to attach.


The block fits a wide range of wire sizes from 22 to 8 American Wire Gauge (AWG), making this a versatile product. The high voltage rating of 800 V means it can safely handle a strong electrical current, so you can use it for large-scale electrical systems like those in commercial and industrial buildings.
