Arrester Selection Guidelines

The following IEEE and IEC summary tables provide key characteristics on Hubbell station arrester designs. Claimable values are made according to IEEE C62.11 and IEC 60099-4. These tables are provided for reference, although arresters with different characteristics such as voltage rating, energy handling capability, strength etc are available upon request. Please contact your Hubbell representative for additional information.
