Product Description
| Product features |
|
●Made of high-quality QA copper wire wound
|
|
●Adopting a broadband magnetic core to synchronize lightning frequency and prevent magnetic saturation
|
|
●This product is applied in scenarios where the decoupling distance of cables between two levels (T1-T2, T2-T2, T2-T3) of lightning protection devices is insufficient, playing a role in energy coordination between lightning protection devices, preventing damage to subsequent lightning protection devices by lightning current, and reducing residual voltage.

●Regularly inspect the product for physical damage or loose connections; replace if faulty.
FAQ
Q1: What is the function of a decoupling device?
A1: It coordinates energy between different levels of SPDs, preventing damage to subsequent SPDs and reducing residual voltage when decoupling distance is insufficient.
Q2: What is the inductive reactance of the product?
A2: The inductive reactance (Ls) is ≥15μH, ensuring effective energy isolation.
Q3: What wiring cross-sectional area is required?
A3: LTS-40A requires ≥6mm² wiring, while LTS-63A requires ≥10mm² wiring.
Q4: Is the product certified?
A4: Yes, it holds TUV and CE certifications, meeting international safety standards.
Q5: Can it be used for DC systems?
A5: No, it is specifically designed for AC 250Vac(50Hz) systems. For DC applications, choose dedicated DC decoupler models.
