High Energy Blocks

High Energy Arrester Blocks (HEB) are designed for installation into the arrester housing. The arrester blocks are installed into the arrester housing and stacked together to achieve higher voltage ratings. The Varsi HEBs provide high peak surge currents and energy rating required for lightning protection of electrical distribution systems.
