LPM H12.5M-280/1+NPE is a T1+T2 level power surge protection device.It adopts a mixed-technology design (MOV for L-N, GDT for N-E) to provide comprehensive protection against direct and indirect lightning strikes.
Featuring module pluggable and anti-vibration design, the product is easy to maintain and replace, making it suitable for industrial and commercial environments. The built-in ultra-low temperature release mechanism ensures safe operation in extreme temperatures. Equipped with visual windows (green: normal; red: failed) and remote signaling contacts, it allows for real-time status monitoring and remote alerts.

Notices
● Install the SPD in LPZ 0A-B or subsequent lightning protection zones to ensure effective T1+T2 protection.
● Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.
● The pluggable module design allows for hot-swapping, reducing downtime during maintenance.
● Regularly check the visual window—replace the module immediately if it turns red (failure status).
● Ensure the grounding system meets requirements (ground resistance ≤4Ω) for optimal surge diversion.
● Confirm the single-phase power system voltage matches 220Vac(50Hz) before installation.
FAQ
