surge protective device(SPD) is designed according to IEC61643
standard. It is accordance with the criterion of Low-voltage Surge
Protective Devices-Part 1: Surge Protective Devices Performance
Requirements and Test Method of Low-voltage Power Distribution
System. With good sealing, it is designed as module and 35mm
din-rail mounting. With working indication window, temperature
control circuit breaker and built-in over-current protective
circuit, this SPD can release automatically to avoid fire danger
when it breaks down. With remote alarm connector, it is convenient
for remote monitoring. The main module and the base are
replaceable. The lightning protection modes is L-PE, N-PE (2P/4P)
or L-N-PE (1+1P) / (3+1P).
These devices protect low-voltage consumer systems from
overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance
varistors permits a rapid response time and a low protection level,
without any line follow current. If circumstances are uncertain and
there is a risk of fire from an overload, the internal cut-off unit
disconnects the arrestor from the mains if necessary. In addition,
the QR code printed on the arrestor allows disary. In addition, the
QR code printed on the arrestor allows direct access to the online
installation instructions.

advantages:
1. Plug-in type surge protective device.
2. Visible window, green means normal, red means fault.
3. Double protection of fusing and over-current.
4. Remote signal interface that realize remote control.
5. Max discharge current can endure 40kA(8/20).
