SV SERIES
SURGE PROTECTIVE DEVICES
Features
● SPD with a fail safe function to prevent
short-circuit (separation of circuit and alarm
contact that is easily to found the timing of
changing the products)
● Compliance with IEC 61643-1 that meets the new
JIS standards
● Against indirect lightning surge for three phase
power supplies
● Quick response for surge
● Impulse current capacity: 8/20μs-5,000A
● Impulse test category: Class II (Type II)
● Every pathway consists of same elements.
Between line and line/between lines and ground
can protect as the same level.
