Is there any side case for Phoenix Contact, Manufacturer part number 1986628?
Welcome to the Tech Forum!
With the ZFKDS 10 series (of which the 1986628, also known as ZFKDS 10-10,00 is a member) one would order a single 1987054 (ZFKDSA10-11,7) double-walled terminal block for a single position or the left-most position of a multiple position array and then as many of the 1986628 single-walled terminal blocks as necessary for the total number of adjacent blocks as needed.
