Product Description
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).
Surge protector is apply for new energy solar power generation system. The maximumcontinuous working voltage of DC500V,100OV and 1200V.Installed on the DC circut power system, the indirect lightning current, DC lightning current or other transient overvoltage prolection when the system or other reasons due to lightning surge overvollage protector, immediately nanosecond time rapid conduction, the over-volage surges into the earth, so as to protect the electrial equipment online.

DC series is plug-in structure,module failure can be quickly replaced: ightning prolection module falure,the inicate window color from green to red and send the alarm signal to theremote connection which in the remote communication terminal of alarm equpment(pus add remote device)
Working Ambient
Ambient temperature is not higher than +40℃,not le than -25℃,relative humidly isnot higher than 95%;
The ocatlon o the instalation height of not more than 2000 metrs;

DC surge protective device is protect against DC power line system and other equipment from over voltage and instantaneous over voltage damage. Widely used in Photovoltaic combiner box, power inverter, DC distribution cabinet etc. It has advantages of large discharge current, fast respond time, low residual voltage.

Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or A powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.
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).
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.

1.Do power off when connect surge protection device to system.
2.Ground wire should be as short, straight and thick as possible to reduce the influence of distributed inductance on lightning discharge.
3.No need special maintenance. When surge protector happens fault,equipment connected to remote signal will send alarm, then power off and change new surge protector module is fine.
