HS-V40D-1K (4 Poles DC Surge Protective Device)

HS-V40D-1K (4 Poles DC Surge Protective Device)

The HS-V40D-1K (4P) is a heavy-duty 4-pole DC surge protective device designed for high-voltage DC systems up to 1000V. With a high discharge capacity of 40kA and a protection level of 2.0kV, it delivers reliable surge suppression for solar PV, battery storage, and DC-powered infrastructure.

Description


Built for advanced DC protection, the HS-V40D-1K (4P) ensures safe and efficient operation in demanding environments such as large-scale photovoltaic systems, energy storage systems, and DC microgrids. Supporting up to 1000V DC (Ucpv) and handling surge currents up to 40kA (Imax), it is designed to protect sensitive components from transient overvoltages caused by lightning strikes or switching operations.

Its low clamping voltage (Up = 2.0kV) ensures minimal stress on downstream equipment, while the 4-pole configuration allows comprehensive coverage in complex DC setups. Compact and easy to install, it is ideal for integration into industrial panels and solar combiner boxes.


Key Features

  • 4-Pole DC Surge Protection – Suitable for complex high-voltage DC circuits
  • High Discharge Capacity – Imax = 40kA
  • Rated Voltage – Ucpv = 1000V DC
  • Low Protection Level – Up = 2.0kV
  • Compact, Rugged Design – Optimized for demanding solar and energy environments
  • Ideal for Renewable Energy Systems – Engineered for solar PV, ESS, and DC power grids

Applications

  • Large-scale solar photovoltaic systems
  • Battery energy storage systems (BESS)
  • High-voltage DC panels and switchboards
  • EV charging infrastructure
  • DC-powered industrial automation

 

The HS-V40D-1K (4P) Surge Protective Device provides powerful 4-pole protection for high-voltage DC systems—ideal for renewable energy and industrial environments where safety and reliability are critical.
