PTG solar DC T2 and T1+T2 SPD adopt Y-type circuit design, and voltage range covers 100 V, 200 V, 300 V, 600 V, 1000 V, 1200 V and 1500 V to meet the requirements of most systems.

The anti-vibration pluggable module design ensures that the module will not loosen even during transportation vibrations or current discharge impacts. Moreover, when it is necessary to replace the module, no tools are required for the operation, making it simple and easy to use, providing a good user experience. The ingenious design of the large arc shield enables rapid heat conduction of low-temperature solder joints and a large creepage distance (>10 mm) after tripping, improving the tripping sensitivity and thereby reducing the risk of fire. The visual status indication of the local red-green window and the switch-type dry contact remote signal alarm effectively monitor the working status of the surge protector. With multiple installation methods, including PCB fixation with a base or without a base, and DIN rail installation, it better meets the requirements of various photovoltaic system scenarios.

The solar DC SPD is used in accordance with the requirements of IEC 61643-32 and is typically installed in the lightning protection zones LPZ 0A-2 and subsequent zones.
