500V LOW VOLTAGE SURGE ARRESTER
Product Picture
Using
Lighting Surge Arrester used to protect electrical equipment from high transient over-voltage hazards caused by lightning, and to limit the free-wheeling time, and often also limits the magnitude of the freewheeling of an electrical appliance. Arrester is also sometimes referred to as overvoltage protector, overvoltage limiter.
Condition of Use
â— The ambient air temperatures is no higher than +40℃, no lower than -40℃.
â— The altitude above sea level do not exceed 2000m.
â— AC system frequency is 50Hz or 60Hz.
â— AC voltage brought to bear on arrester for a long time does not exceed arrester's continuous operating voltage.
â— Maximum wind speed does not exceed 35m/s.
â— The earthquake intensity does not exceed 7 degrees.
