ED80 Series

ED80 types are heavy-duty metal oxide varistors designed mainly for industrial applications. They are equipped with thermo decoupling device and remote signalisation. They offer excellent surge protection for various electronic equipment: windmills, traffic and railway signal systems, communication equipment, waterworks, automatic control devices for power distribution, oil drilling and mining equipment (dredgers, cranes, etc.).

ED80 housings offer an excellent protection also when they are exposed to different kinds of vibrations, dust, moisture, etc.

The advantages of the ED80 Series are: rigid terminals for good wire contact, a thermo decoupling device which protects ED80 from varistor failure in event of abnormal overvoltage; ED80 has also a remote signalisation capability with remote terminals and galvanic separation from main line, solid plastic housing for secure mounting, higher insulation resistance (polyurethane filling and plastic housing).
