Publication CODE Title
NBN EN 61643-311:2013 (2013-08) COMPONENTS FOR LOW-VOLTAGE SURGE PROTECTIVE DEVICES PART 311: PERFORMANCE REQUIREMENTS AND TEST CIRCUITS FOR GAS DISCHARGE TUBES (GDT)
 
Price Excl. VAT Total number of pages, tables and drawings
25.00 € 3 P..
Description
Is applicable to gas discharge tubes (GDT) used for overvoltage protection in telecommunications, signalling and low-voltage power distribution networks with nominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c..They are defined as a gap, or several gaps with two or three metal electrodes hermetically sealed so that gas mixture and pressure are under control. They are designed to protect apparatus or personnel, or both, from high transient voltages. This standard contains a series of test criteria, test methods and test circuits for determining the electrical characteristics of GDTs having two or three electrodes. This standard does not specify requirements applicable to complete surge protective devices, nor does it specify total requirements for GDTs employed within electronic devices, where precise coordination between GDT performance and surge protective device withstand capability is highly critical. This edition of IEC 61643-311 cancels and replaces the first edition published in 2001. It constitutes a technical revision. Specific changes with respect to the previous edition are: Addition of performance values.
