Detailed Product Description

LPM H12.5M-280/3+NPE is a T1+T2 level power surge protector designed for three-phase power supply systems.

It adopts a mixed-technology design (MOV for L-N, GDT for N-E) to provide comprehensive protection against direct and indirect lightning strikes.

Benefits
Minimize Downtime: Hot-swappable modules let you replace faulty units in minutes, no power shutdown required, even in high-vibration industrial environments.	Operate Safely in Extreme Cold: The ultra-low temp release mechanism ensures reliable protection down to -40°C, eliminating cold-start failures.	Proactive Maintenance: Real-time status windows and remote alerts let you monitor health remotely, so you can fix issues before they cause outages.

Application scenarios

Suitable for installation in LPZ 0A-B and subsequent lightning protection zones to ensure effective T1+T2 protection.

Installation Tips

1.Install the SPD in LPZ 0A-B or subsequent lightning protection zones to ensure effective T1+T2 protection.

2.Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.

3.The pluggable module design allows for hot-swapping, reducing downtime during maintenance.

4.Regularly check the status window; replace the module immediately if it turns red (failure status).

5.Ensure the grounding system meets requirements (ground resistance ≤4Ω) for optimal surge diversion.

6.Avoid using the product in environments with strong vibration beyond its anti-vibration capacity.

FAQ

Q1: What is the mixed-technology design of the product?
A1: It uses MOV (Metal Oxide Varistor) for L-N protection and GDT (Gas Discharge Tube) for N-E protection,

combining the advantages of both technologies for optimal performance.

Q2: What is the function of the pluggable module design?
A2: Yes, the pluggable module design allows for hot-swapping, enabling module replacement without disconnecting the power supply.

Q3: What is the anti-vibration design used for?
A3: It ensures the product operates stably in industrial environments with vibration, such as manufacturing plants and power plants.

Q4: What is the difference between L-N and N-E response times?
A4: The L-N response time is ≤25ns (faster for line-neutral surges),

while the N-E response time is ≤100ns, matching the characteristics of different surge paths.

Q5: Can it be used in solar power systems?
A5: Yes. It is suitable for three-phase power systems in solar parks, providing comprehensive lightning protection for inverters and distribution systems.
