HD-T1-SPC/240

This product is designed for low-voltage output of the main power switchgear to protect the rear-end equipment from direct lightning strikes or fault overvoltage surges introduced from the high-voltage side. This product uses a sealed structure that can be used in a variety of extreme environments to maintain excellent performance, with explosion-proof, waterproof, moisture-proof and anti-corrosion effects. It can be applied to various fields such as wind energy, solar energy, petrochemical, mining, and electric power. This product adopts high-energy type semiconductor device, low residual voltage, impact resistance, installed in sealed metal casing, self-heating function and over-current over-current tripping function, which can function as explosion-proof and fireproof.
