Radial Lead Varistor (MOV)
1304DS Series
Description
34S series transient surge suppressors are industrial high
energy Metal-Oxide Varistors (MOVs). They are designed to
provide secondary surge protection in the outdoor and service
entrance environment (distribution panels) of buildings, and
also in industrial applications for motor controls and power
supplies used in the oil-drilling, mining, and transportation
fields.
The maximum peak surge current rating can reach up to 40KA
(8/20μs pulse) to protect against high peak surges, including
indirect lightning strike interference, system switching
transients and abnormal fast transients from the power
source.
