“ZNR” Transient/Surge Absorbers (Type J)

“ZNR” Transient/Surge Absorbers (Type J)
“ZNR” Transient/Surge Absorbers
Type : J
ZNR Transient/Surge Absorbers, Type J, are designed
especially for surge protection of industrial equipment
from high energy transient voltages which are generated
by switching of the inductive loads such as DC magnet
relays or transformers.
Features
● Low
clamping voltage
response to steep impulse voltage
● A bilateral and symmetrical V-I characteristic curve
● Higher energy handling capability (5000 to 44000 J)
● No follow-on current
● Wide product range
[Varistor Voltage] 500 V to 1300 V
● RoHS compliant
● Fast
Recommended Applications
● Suppression
of volume surges such as those produced by switching of DC lifting magnets and within
equipment in railroad vehicles
● Protection of a current transformer from overheating caused with secondary opening
● Protection of thyristors or diodes employed in power supply equipment
Note: Ask our factory for Product Specification before use.
