The 0.156" (3.96mm) pitch sets the PCB footprint and the per-contact current ceiling — at the rated voltage of 600VAC, the current is limited by the wire gauge used, not the header itself.
Tin avoids the cost premium of gold and is compatible with the tin-plated terminals in the MTA-156 receptacle.
The pin pitch is 0.156" (3.96mm), which is the standard for the MTA-156 series. This sets the PCB footprint and the spacing for the mating receptacle.
