Varistors (ZNR Surge Absorber) Type E/J Varistors (ZNR Surge Absorber) For Thyristor Protection Type: E Type: J Type Type J Varistors (ZNR Surge Absorber) for thyristors is especially designed to protect SCR power controllers and SCR power sources from high energy transient over voltages. The ZNR is smaller in size and excellent in the clamping voltage characteristics as compared with a conventional selenium surge absorber. Type E is for relatively low handling capacity of trans-former and Type J is for heavy duty use. RoHS compliant Recommended Applications Surge protection of SCR power controllers Surge protection of SCR power sources SCR = Silicone Controlled Rectifiers Note : Ask our factory for Product Specification before use. As for Handling Precautions and Minimum Quantity / Packing Unit Please see Related Information Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
