keyword 2-pole threaded DC discharge starting voltage 800V
Product Info Product name: Y49-800L
Item code: 11005394

Mounted between the neutral line and ground of the communication circuit board and power supply circuit of the 2-pole arrester (GDT) communication device, and used to protect the device from induced voltage and TOV (temporary overvoltage) induced in the line to do.

Compared to other products, it has a very large current capacity (8 / 20µs, 40kA).

Main applications

  • Various electronic devices
  • Communication line protection
  • AC power supplies
  • Inverters

Notes on use

When using this product for AC power, be sure to use it together with a varistor.

If the arrester is used alone, a follow current may occur.

We also have AV series (2 poles) and AV3P series (3 poles) with arresters and varistors integrated.
