SHIHLIN Surge Protective Device

Surge Protective Device

Feature

  1. Suitable for AC220V/380V, 50/60Hz power system.
  2. Low residual voltage and low leakage current.
  3. Thermal trip/fuse function for fast response.
  4. Plug-in modular design for easy installation and replacement.
  5. Standard 35mm din-rail installation.
  6. Status window display
  7. Additional alarm switch can be added.

Electrical Characteristics

  1. SPD structure: Inner core part is a metal oxide varistor made with zinc oxide.
  2. Rated voltage (Un): The rated voltage of SPD device will be the same with rated voltage of the device being protected.
  3. Maximum continuous operating voltage (Uc): 275VAC, Uc should be 15% greater than Un.
  4. Frequency: 50/60 Hz
  5. Time: MOV≦25ns, NPE≦100ns
  6. Voltage protection level (Up): Less than rated impulse withstand voltage of the device being protected.
  7. Life expectancy: It takes voltage surge 10000 times within rated discharge current
  8. Operating temperature: -5˚C ~ +40˚C, relative humidity: 30~99%, operating altitude: 2000 meter below.

 

Operating Principle

  1. Voltage limiting type SPD: Having high impedance when no surges occur and as the surge voltage and current increase, the impedance decrease. By using varistor and transient voltage suppressor (TVS).
    Leakage current is limited, with fast response time and low residual voltage.
  2. Voltage switching type SPD: Having high impedance when no surges occur and become low impedance when surges occur. Use spark gap and gas discharge tube type parts. Voltage discharge capability is high.
