The C-III Varistor Series of Metal-Oxide Varistors (MOVs)
are specifically designed for applications requiring high
surge energy absorption ratings and superior multiple
pulse absorption rating. This is achieved through a special
dielectric material formulation which also results in
higher repetitive surge ratings than other MOV types.
The C-III Varistor Series is primarily intended for use in
AC line Surge Protection Device (SPD) product and other
similar applications requiring high transient energy and
peak current capability in a relatively small package size.
