Product Info | Product name: Y49-550L Item code: 11009303 |
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.
Main applications
- Various electronic devices
- Communication line protection
- AC power supplies
- Inverters
- Low capacitance
- Broadband compatible

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.
