High Light 3 phase whole home surge protector ，T2 SPD lightning protection box ，220V surge protector with warranty
LPX-40C is a dedicated three-phase AC surge protection device engineered to shield three-phase power systems from transient overvoltages triggered by lightning strikes and grid fluctuations, delivering all-round protection for critical power infrastructure.


 
Benefits
Industrial-Grade Stability: Built with optional mode protection and rugged PCB design, delivering consistent, interference-free performance in demanding industrial environments.
Precise Surge Counting: Integrated lightning counter (3kA–80kA, 0–999 digits) accurately records surge occurrences, supporting data-driven predictive maintenance.
Remote Monitoring:Remote signaling and visual status indicators enable real-time operational visibility and centralized management of protection status.
 

Applications

Designed for installation in LPZ 1–2 and subsequent lightning protection zones, providing fire-safe surge protection for three-phase power distribution systems.

Installation Tips
  • Install the lightning protection box in a dry, well-ventilated indoor location, and keep it clear of flammable substances.
  • Use conductors with a cross-sectional area of 2.5mm²–10mm², and tighten terminal screws to a torque of 5N·m.
  • Ensure a reliable earthing connection with a ground resistance of ≤4Ω to achieve optimal surge discharge efficiency.
  • Inspect the lightning counter and status indicator regularly: if the indicator is off, the device has failed and must be replaced promptly.
  • Do not connect the unit to a power supply exceeding its rated voltage or current limits.
  • Avoid operating the product outside its specified temperature and humidity ranges.
FAQ
Q1: What is the counting range of the lightning strike counter?
A1: The counter can record lightning events with a discharge current of 3kA(8/20μs) to 80kA(8/20μs), and the digital display range is 0 to 999.
 
Q2: Does the product support remote monitoring?
A2: Yes. It is fitted with both normally closed and normally open remote signaling contacts, allowing integration with monitoring systems for remote status tracking.
 
Q3: What is the difference between LPX-40C and LPX-80C?
A3: The primary difference is the maximum discharge current (Imax): LPX-40C has an Imax of 40kA, while LPX-80C offers 80kA, catering to different levels of system protection requirements.
 
Q4: Can it be installed in outdoor environments?
A4: No. This model is designed exclusively for indoor use. For outdoor applications, please select products with an IP67 ingress protection rating.
