These coordination inductors are specially designed to control the implementation of the primary and secondary levels of SPD surge protectors. They are necessary where the coordination cannot be accomplished using the 'natural' inductance of the active conductors (in particular in a small volume, where the length of line wire between primary SPD and secondary SPD is lower than 10m), DSH inductors are DIN rail compatible and are connected in series on the line to be protected and depend on the maximum line current.
