Terminal block Weidmüller WDU 10 and WQV 10/2

[bsilveira]

Good day

1. Could you please advise if terminal block Terminal block Weidmüller WDU 10 – 1020300000 can handle connections of two conductors of 10mm2 cross section area at single point of connection. Is this type of connection allowed as per electrical standard or do we need to use jumper like WQV 10/2?
   
   
2. Are WQV 10/2 jumper compatible to be used with WDU 10 in terms of current carrying capacity and voltage?
   Regards
   Ben

Hello bsilveira,
Welcome to the TechForum.
According to the datasheet, the terminal block 281-1470-ND ratings are shown in the below snippet. As far as the electrical standards for using two conductors at the same time from what I was able to find, the terminal has to say that it allows it to be up to code and I couldn’t find any documentation on this block saying that.

As far as using 281-1522-ND with this terminal block here is snippet of its ratings as found on the datasheet.
