RUILON 2R600-12D-LW0

Gas discharge tubes (GDTs) normally maintain a high-impedance state, equivalent to an open circuit, with negligible impact on normal circuit operation. When a transient overvoltage occurs and its amplitude exceeds the GDT's breakover voltage, the gas inside ionizes, causing the GDT to conduct rapidly and clamp the overvoltage to a lower level, thereby protecting parallel-connected electronic equipment or circuit components from high-voltage surge damage. Once the overvoltage subsides, the GDT immediately returns to its high-impedance state and normal circuit operation resumes. The 2R-12D series is a GDT with follow current cutoff capability, manufactured using advanced processes and high-quality materials, offering excellent durability and reliability. Its compact structure allows easy installation in various power supply equipment. Fast response speed provides reliable protection for electronic devices and ensures stable operation of power systems. In AC power applications, it delivers superior follow current cutoff performance — upon the occurrence of abnormal follow current, it can interrupt quickly and decisively to prevent follow current hazards and ensure circuit safety. The 2R-12D series features high surge current handling capability and is suitable for N-PE protection.
