NF C61-743-311*NF EN 61643-311:2014 Components for low-voltage surge protective devices - Part 311 : performance requirements ans test circuits for gas discharge tubes (GDT)
This part of IEC 61643 is applicable to gas dis harge tubes (GDTs) used for overvoltage protection of low-voltage telecommunications, signal and dis ribution networks, the rated network voltages of which are less than or equal to 1 000 V (rms values) AC and 1500 V DC They are defined as a spark gap or spark gaps with two or three metal electrodes hermetically sealed so that the gas mixture and pressure are under control. They are designed to protect equipment or people, or both, against high transient overvoltages. This standard contains
