  • Nominal Discharge Current (In): 20kA (8/20µs) for strong performance during surge events.
  • Maximum Discharge Current (Imax): 40kA (8/20µs) for handling high surge capacities.
  • Voltage Protection Level (Up): ≤ 1.4kV, ensuring minimal residual voltage to protect connected equipment.
  • Response Time: < 25ns, providing rapid action to mitigate voltage spikes.
  • Operating Temperature Range: -40°C to +85°C, suitable for various climatic conditions.
  • Enclosure Material: Thermoplastic, UL94-V0 flame retardant for enhanced safety.
  • Connection Type: Pluggable module for easy installation, maintenance, and replacement.
  • Visual Fault Indicator: Clear status indication for straightforward monitoring and maintenance.
  • Standards Compliance: Meets IEC 61643-31 and UL 1449 4th edition standards, ensuring high-quality and reliable performance.

These features combine to make the Citel DS240S-280DC SPD a reliable and efficient solution for protecting photovoltaic systems and other DC applications from damaging transient overvoltages.
