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
● The ambient air temperatures is no higher than +40℃, no lower than -40℃.
● The altitude above sea level do not exceed 2000m.
● AC system frequency is 50Hz or 60Hz.
● AC voltage brought to bear on arrester for a long time does not exceed arrester's continuous operating voltage.
● Maximum wind speed does not exceed 35m/s.
● The earthquake intensity does not exceed 7 degrees.
