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, plugged module.
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 signaling contact optional.
6. Voltage can be customized.
7. T1+T2lightning protection.
