HS-V40D-1K (2 Poles DC Surge Protective Device)

HS-V40D-1K (2 Poles DC Surge Protective Device)

The HS-V40D-1K (2P) is a high-performance 2-pole DC surge protective device designed for photovoltaic and other high-voltage DC systems. With a Ucpv of 1000V DC, 40kA discharge capacity, and 2.0kV protection level, it ensures reliable protection against overvoltage surges in critical DC circuits.

Description


The HS-V40D-1K (2P) is purpose-built for DC applications, offering robust surge protection for systems operating up to 1000V DC. It supports a maximum discharge current (Imax) of 40kA, making it ideal for solar PV systems, battery storage solutions, and DC power distribution units.

Its low protection voltage (Up) of 2.0kV helps minimize the risk of damage to connected equipment during transient events such as lightning strikes or switching surges. Compact, durable, and easy to install, this SPD is designed for reliable long-term operation in harsh environments.


Key Features

  • 2-Pole DC Protection – Engineered for high-voltage DC circuits
  • High Surge Capacity – Imax = 40kA
  • Rated Voltage – Ucpv = 1000V DC
  • Low Clamping Voltage – Up = 2.0kV
  • Compact and Durable Design – Ideal for industrial and outdoor panels
  • Photovoltaic System Ready – Suitable for solar and energy storage systems

Applications

  • Solar PV string protection
  • Battery storage and inverter systems
  • DC power distribution boards
  • EV charging infrastructure
  • Industrial automation with DC supplies

The HS-V40D-1K (2P) Surge Protective Device provides powerful and precise protection for high-voltage DC applications—ensuring system safety and stability in solar, industrial, and energy-critical environments.
