LTS-40A/LTS-63A Decoupling Device is designed for scenarios where the decoupling distance between two levels of surge protectors (T1-T2, T2-T2, T2-T3) is insufficient. It plays a key role in energy coordination between SPDs, preventing subsequent SPDs from damage caused by lightning current and reducing residual voltage.
Crafted with high-quality QA copper wire winding and a broadband magnetic core, the product synchronizes with lightning frequency to avoid magnetic saturation. This design ensures stable inductive reactance (≥15μH) even under surge conditions, effectively isolating energy between different levels of SPDs.

Notices
●Install the decoupler between two levels of SPDs to ensure sufficient energy coordination.
●Select the model based on the system's maximum load current (40A/63A).
●Use wiring with cross-sectional area ≥6mm² (LTS-40A) or ≥10mm² (LTS-63A) and tighten screws to 5N·m torque.
●Ensure the installation environment meets temperature (-40℃~+80℃) and humidity requirements.
●Avoid installing in environments with strong electromagnetic interference to prevent performance degradation.
●Regularly inspect the product for physical damage or loose connections; replace if faulty.
