.Gas Discharge Tube Arresters (GDT)Gas discharge tubes (GDTs) are specialized electrical components that are designed to limit the voltage on a circuit, particularly circuits exposed to high frequency electrical noise, high voltage impulses, and lightning strikes. GDTs are often used in the protection of telecommunication equipment, AC power lines, and other equipment in industrial environments. The GTCT37-401M-P10 is a GDT designed to provide enhanced protection to both AC and DC power circuits.The GTCT37-401M-P10 offers both protection from high voltage and from over-current for AC applications. This device also provides additional protection from high DC voltage. Its second operating stage, or Zener breakdown voltage, provides power over-voltage clamping protection from DC over-voltages up to 600V. In terms of current handling capability, the GTCT37-401M-P10 has an internal resistance of 10Ω at 25℃, and can handle several kilo Amps of current.In operation, the GTCT37-401M-P10 uses two stages of breakdown to protect the system by providing a clamping action to reduce the voltage across the protected circuit. The first stage, or the avalanche breakdown voltage, typically occurs at 20V and offers protection from over-voltage. The second stage, or Zener breakdown voltage, provides power over-voltage clamping protection from DC over-voltages up to 600V.The GTCT37-401M-P10 is an effective device for applications requiring transient voltage surge protection, with an operating temperature range of -40℃ to 85℃. It provides superior reliability and excellent noise suppression, with a nominal response time of 0.35µs. Its internal components are fully insulated and hermetically sealed, ensuring it will stay in top condition, even in harsh environments.The GTCT37-401M-P10 is commonly used in Industrial control systems, as well as in telecommunications, power supply, and instrumentation equipment. Its over-voltage protection assists in protection against lightning strikes, over-voltage surges, and voltage transients. It can also provide over-current protection and load-limiting protection, protecting against short-circuit currents.In summary, the GTCT37-401M-P10 is a highly effective Gas Discharge Tube Arrester (GDT). It provides protection from high voltages, over-currents, lightning strikes, and voltage transients. This device is an excellent choice for applications needing protection against voltage or current fluctuations, or for those incorporating AC or DC devices. Its superior reliability and excellent noise suppression make it an ideal choice for applications in telecommunications, industrial control, power supply, or instrumentation.
