The ASIUK3MVSTB508 pluggable terminal block has a current rating to 20 A at 300 V and a wiring capacity of 26 to 12 awg.
It mounts on a DIN rail, but unlike conventional blocks, there is a pin header on one side on 5.08-mm spacing that accepts the plug-in block. The unit's vertical connector entry provides for a complete circuit from 2 to 20 positions to be mated and unmated in one action. Both the plug and terminal block are polarized so mating is only in one direction.
