Product Details

Metal Oxide Varistors HighE Series

The E series are heavy-duty metal oxide varistors designed mainly for industrial applications. They offer excellent surge protection for various electronic equipment such as: traffic and railway signal systems, communication equipment, waterworks, automatic control devices for power distribution, oil drilling and mining equipment (dredgers, cranes, etc.). The E housing offers excellent protection when exposed to different kinds of vibrations, dust, moisture, etc. The advantages of the E Series are: rigid terminals for secure wire contact, solid plastic housing for secure mounting, higher insulation resistance (polyurethane filling and plastic housing).
