LD-MD series primary surge protective device (SPD) is designed according to IEC and GB standards. It is applied to the first-level surge protection of the power supply system. The SPD uses a standard 35mm rail type installation method.
The LD-MD series T1 level surge protector has a high lightning current discharge capacity. The maximum impulse current of a single module can reach 50KA (10/350μs), which can prevent various surges including direct lightning. It is applied to be the first-level surge protection device in power supply equipment systems in the areas of higher risk of lightning strikes. It can be combined for single-phase/three-phase power supply lines.
