PRODUCT DATASHEET LY1-C40 AC Surge protective device
Application
This AC surge protective device is applied low voltage standard IEC EN 61643-11 to protect against AC power line system and other equipment from over voltage and instantaneous over voltage damage. It has advantages of large discharge current, fast respond time and low residual voltage.
Main features
1. High discharge capacity, quick response, pluggable.
2. Fast response time, din rail installation.
3. Double thermal disconnection devices, provide more reliable protection.
4.Green window means normal, red means defect, need to change module.
5. Remote alarm terminal optional.
6. Voltage can be customized.
