Abstract

Applies to two or three terminal, four or five layer, thyristor surge protection devices (SPDs) for application on systems with voltages equal to or less than 1000 V rms or 1200 V dc. These protective devices are designed to limit voltage surges on communication circuits and power circuits operating from a direct current (dc) to 420 Hz. Included in this standard are definitions, service conditions and a series of test criteria for the determining of characteristics of a thyristor SPD. If the characteristics differ with the direction of conduction then each polarity will be specified separately.
