ABSTRACT:
An improved apparatus and method for encapsulating a single large MOV is shown. The MOV is sandwiched between aluminum contact plates. An epoxy fills the void space between the contact plates. A dielectric film encapsulates the entire sandwich. Soft films of aluminum foil or a deposition coating is used to cover the MOV surface to cure facial defects. An optional exterior case protects the MOV assemblies contained therein from short circuits due to dirt, grease or water build-up. The apparatus is designed to withstand over 100,000 amps of surge in a commercial up to 220 volt per phase secondary power system.
