“ZNR” Transient/Surge Absorbers (Type E/J)
ÒZNRÓ Transient/Surge Absorbers,
For Thyristor Protection
Type: E
Type: J
ÒZNRÓ Transient/Surge Absorber for thyristors is
especially designed for protection of SCR power
controllers and SCR power sources from high energy
transient overvoltages.
The ZNR is smaller in size and more excellent in the
clamping voltage characteristics as compared with a
conventional selenium surge absorber. The ZNR
Type E is for a relatively low handling capacity of trans-
former and Type J is for a heavy duty use.
Type E
Type J
nRecommended Applications
lSurge protection of SCR] power controllers
lSurge protection of SCR] power sources
]SCR = Silicone Controlled Rectifiers
