Description

New IEEE Standard – Inactive – Superseded. Superseded. Gas-tube surge-protective devices for application on systems with voltages 1000 V rms or 1200 V dc are covered. These protective devices are designed to limit voltage surges on balanced or unbalanced communication circuits and on power circuits operating from dc to 420 Hz. Test criteria for determining the electrical characteristics of these devices are provided.
