40KA 1000V 2P 3P Solar DC Surge Protective Device SPD

As a global leader in the solar industry, Mindian offers a comprehensive line of Surge Protection Devices (SPDs), and related assemblies. The MDSP-600 has the advantages of a fail-safe and self-protecting design, visual indicators and small size. The DC SPD 600V series of arresters are carefully calibrated according to recent technological advancements and our surge protectors can reach a continuous maximum operating voltage of 1000V. In addition, the arresters are equipped with high-voltage sensors to effectively detect faults, and are made of high-quality materials to protect against damage caused by weather and lightning.

MOREDAY three-module photovoltaic Surge Protective Device (SPD) (with three-step DC switching device) features visual indication and optional remote contact signaling (floating changeover contact) for use in PV systems. These complete surge protective devices are suitable for all PV systems in accordance with IEC 60364-7-712. Includes a five year limited warranty.

These pre-wired solutions consist of a base and locking modules that feature a combined disconnection and short-circuiting (shunting) device with safe electrical isolation to prevent fire damage due to DC arcs. An integrated DC fuse allows safe module replacement without arc formation. In case of insulation faults in the generator circuit, a reliable and tested fault-resistant `l circuit prevents damage to the surge protective devices.

The green and red visual indicator flags show the module protective status (green = good, red = replace). Apart from this visual indication,the remote signaling option features a three terminal floating changeover contact that can be used as a make or break contact depending on the particular monitoring system design employed.
