Product Description
Crafted with high-quality copper wire winding and a broadband magnetic core, this decoupling device is engineered for scenarios where the cable decoupling distance between two levels of surge protection devices (SPDs, e.g., T1-T2, T2-T3, T2-T1) is insufficient. It acts as a key component in energy coordination between SPDs, preventing subsequent SPDs from damage caused by lightning current and reducing residual voltage.
| 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.

5.Electromagnetic Environment: Avoid installing in areas with strong electromagnetic interference to prevent performance degradation.
6.Regular Inspection: Regularly check the product for physical damage or loose connections; replace the device immediately if a fault is detected.
FAQ
Q1: What is the function of this decoupling device?
A1: It coordinates the energy between two levels of SPDs, preventing damage to subsequent SPDs caused by lightning current and reducing residual voltage when the cable decoupling distance between SPD levels is insufficient.
Q2: What is the inductive reactance of this product?
A3: LTS-40A requires 6mm² wires, while LTS-63A requires 10mm² wires.
Q4: Can it be used for DC systems?
A4: No. This product is specifically designed for AC 250Vac(50/60Hz) systems. For DC applications, please choose our dedicated DC decoupler models.
