keyword 2 poles No lead wire DC discharge starting voltage 250V
Product Info Product name: Y20-250A
Item code: 11010728

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, maximum 80kA).

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.
