|
METAL TOP LINE TERMINALS: Accommodates 14 through 335 mm2 copper or aluminum conductor.
METAL-OXIDE VALVE DISK (INTERNAL): Specially formulated metal-oxide compound provides exceptional non-linear electrical characteristics for ideal energy-absorbing protective levels.
PORCELAIN-HOUSING: Withstands thermal and electrical shock; excellent self-washing characteristics; skirts designed to provide high creepage distance.
PRESSURE-RELIEF SYSTEM: Pressure actuated system assures maximum safety and reliability; vent covers prevent foreign material from entering vent ports and indicate operation.
VariSTAR AZG3 Surge Arresters offer the latest in metal oxide varistor (MOV) technology for the economical protection of medium-voltage class power and substation equipment. These arresters are gapless and are constructed of a single series column of 63 mm diameter MOV disks.
The arrester is designed and tested exclusively to the requirements of the International Electrotechnical Commission Standard IEC 99-4, and is available in ratings suitable for the transient overvoltage protection of electrical equipment on systems through 345 kV.
