2-electrode GDT These products are intended for the protection of telecommunications or dataline equipment. The Maximum impulse sparkover voltage of the products are 90 to 3500 V. These products are available in version: through hole and surface mounting. The Safety Disconnect (FL) option is offered.

3-electrode GDT. These products are intended for the protection of telecommunications or dataline equipment. The Maximum impulse sparkover voltage of the products are 90 to 700 V. These products are available in version: through hole and surface mounting. The Safety Disconnect (FL) option is offered.

Based on CITEL's experience and knowledge in the field of gas dischage tubes, CITEL has developed a specific technology: GSG (Gas-filled Spark Gap). These components are specifically designed to be used on AC or DC power networks. The GSG product has an optimized extinction capability and a higher current discharge capability with either a 8/20µs or 10/350µs waveform.

These spark gaps are designed to protect metallic elements, like antennas, poles, pipes, and roofing equipment which are not connected to earth or a Lightning Protection System against the risk of a flashover during a lightning strike.
