30 Position 24Amp/400V Screw Terminal Block Distribution Module (Screw Mount)

You can remove the board from the rail mount and use screws, worked great for all the inputs/outputs on my arduino project.

I needed to splice a 30 wire cable and this provided a robust and simple solution

This is a very well built block. I used it to terminate five six conductor runs and 20 g solid core wire and it performed flawlessly. On the other side of the block I doubled up two 16g wires as a jumper and that was doable but a little tight.

Used to buy the individual terminals, but these are way more convenient, cost less and look cleaner in the installation in my opinion. Would like to be able to jump terminals with a cap. Not sure if that is a feature this design has and they don't provide the jumpers, or if this isn't possible at all with this block aside from using wires to jump at the terminals. Would be much more useful with top mount jumper strips, only reason for 4 stars. If that's a feature and someone corrects me, I'll bump up to 5 stars. Way better build quality than others I've seen. Pretty close to the same as what came in some of my high end industrial cabinet shop equipment.

This product worked great for my purpose. I wanted a way to connect many alarm wires that were coming into a metal enclosure that would look clean and be easy to work on if needed later. This did the trick for me.

Used to collect and organize connections of low-voltage wiring in complex model railroad layout.

Great board. Does exactly what I needed. Will be ordering more.

Made very well. Quality seems good I would buy again.
