The V series is a standard metal oxide varistor series from UCC/NCC that are designed for use as
surge protectors in general purpose applications. These MOVs are a smaller size and have higher
energy and surge ratings compared to the G series. The varistors with a 5mm or 7.5mm lead spacing
are available with ammo pack taping.
Refer to the Mini -Glossary at the end of the metal oxide varistors section for additional technical
information and specifications.
