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. Product Features
Wide-Range Application Scenarios
Suitable for LPZ 0A-B and subsequent Lightning Protection Area
installation, used as a single-phase power supply
system lightning arrester.
Product Specification
Mechanical parameters
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 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: Does the product support hot-swapping? 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 environments with slight vibration, such as small workshops and commercial buildings.
Q4: Can it be used for household air conditioners and refrigerators? A4: Yes, it is suitable for protecting household appliances with single-phase power supply, providing comprehensive lightning and surge protection.
Q5: What is the size of the product? A5: The product size is 90mmx36mmx80mm, compact and suitable for installation in small distribution boxes.
