Stud Configurations

Studded power blocks are part of our traditional NEMA style offering.

These power blocks provide studs, or a combination of bare wire terminals with the stud, to terminate crimp lugs or bus bar to our power blocks to splice or distribute power.

Marathon Special Products has been an industry leader for supplying power blocks in North America since 1955. We have achieved this by providing one of the broadest line offerings with various sizes, terminal styles, electrical ratings and features.
