Electrical Surge Protection Decoupler 40A 15μH DIN Rail T1 T2 SPD Coordination Industrial Protection

Price Negotiable
Price: US $13-16/Piece
MOQ: 1 piece
Delivery Time: 7-15 days
Brand: LLH
Product Description
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.
 
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.

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.

 

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.
