Surge protector device (SPD) 500V DC

500V DC Surge Protective Device (SPD) is a critical safety component designed to protect solar photovoltaic (PV) systems, inverters, and battery storage banks from high-voltage surges caused by lightning strikes or systemic switching events Key Features Voltage Rating: 500V DC (maximum continuous operating voltage or Discharge Capacity: Typically rated between 20kA to 40kA (Nominal to Maximum Discharge Current). Response Time: Rapid clamping mechanism acting within 25 nanoseconds to suppress surges before they hit sensitive inverter circuits.
