Marathon Special Products is proud to introduce our new studded power feedthru terminal blocks. The ST722 terminal block is an economical solution for any feed-thru application requiring termination of double hole lugs with a center line of .625". By having three unique mounting styles and various line lengths to choose from, the ST722 can simplify your design requirements. The conductor, is a one-piece, brass tin-plated, 1/4"-20 threaded stud, which eliminates current path issues. Furthermore, the threaded studs are designed with the length necessary to allow thick lugs and still have ample thread engagement of the nut. The insulator base is molded of an engineered glass filled polycarbonate which provides an excellent balance of strength, flexibility, flammability (UL 94 V-0) and temperature resistance to 125°, while remaining ductile enough to withstand most stresses. An optional opaque cover is available for all line lengths with easy "snap-on" design and can be removed by lightly squeezing the outside barriers. In addition, with the terminal barrels (lugs) properly insulated, an IP2 rating may be achieved when using the cover. The cover is a one-piece design molded of high temperature thermoplastic, which has a flammability rating of UL 94 V-0.
