Description
LTS-40A/LTS-63A Decoupling Coil
Crafted with high-purity oxygen-free copper wire winding and a broadband magnetic core, this decoupling device is purpose-built for scenarios where the cable decoupling distance between two tiers of surge protection devices (SPDs, e.g., T1-T2, T2-T3, T2-T1) is inadequate. It serves as a critical component in energy coordination between SPDs, safeguarding downstream SPDs from lightning-induced current damage and minimizing residual voltage levels.
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.

Installation Tips

1.Energy Coordination Function: This decoupling device enables effective energy coordination between two SPD tiers, ensuring proper protection coordination across the system.

2.Model Selection: Choose the appropriate model (40A or 63A) based on the system’s maximum load current requirement.

3.Wiring Requirements: Use conductors with the specified cross-sectional area: 6mm² for LTS-40A and 10mm² for LTS-63A. Tighten the terminal screws to a torque of 5N·m.

4.Environmental Conditions: Ensure the installation environment meets the specified temperature range (-40°C to +80°C) and humidity requirements.

5.Electromagnetic Compatibility: Avoid installation in areas with strong electromagnetic interference to prevent performance degradation.

6.Regular Inspection: Routinely inspect the product for physical damage or loose connections. Replace the device immediately if any fault is detected.

FAQ

Q1: What is the core function of this decoupling device?

A1: It coordinates the energy between two tiers of SPDs, preventing damage to downstream SPDs caused by lightning current and reducing residual voltage when the cable decoupling distance between SPD tiers is insufficient.

Q2: What is the inductive reactance value of this product?

A2: The inductive reactance (Ls) is ≥15μH, which ensures effective energy isolation and coordination between SPD tiers.
Q3: What wire cross-sectional area is required for installation?

A3: LTS-40A requires 6mm² wires, while LTS-63A requires 10mm² wires for optimal performance.

Q4: Can this device be used in DC power systems?

A4: No. This product is specifically designed for AC 250Vac (50/60Hz) systems. For DC applications, please select our dedicated DC decoupling coil models.
