The MidNite MNSPD300AC is a great replacement for Delta arrestors that have been the mainstay of the industry for many years. The MidNite surge protectors are designed to clamp surge voltage to safe levels for sensitive electronics.

The MidNite Solar Surge Protector Device (MNSPD) is a Type 2 device per UL1449 rev3. It is designed for both AC and DC systems and provides protection to service panels, load centers or where the SPD is directly connected to the electronic device requiring protection.

Listed by ETL for US & Canada





Selecting the Proper Voltage Surge Protector:

The MidNite Solar SPD is offered in three different voltages to maximize the required protection level. Protection is achieved by reducing the clamping voltage to a safe voltage that your system can sustain without damaging any electronics in the system. By using the chart below select the SPD’s that provide the protection your system requires. If you have questions or need assistance selecting the correct unit don't hesitate to contact us.
