Detailed Product Description

About this item

50kA surge handling capacity (8/20μs & 10/350μs) with ≤1.5kV protection level, shielding three-phase power systems from lightning and overvoltage.

● Full-mode protection (L1-N/L2-N/L3-N/N-E) eliminates blind spots, compatible with LPZ 0A-B lightning protection zones.

≤25ns fast response time, no leakage current, ensuring stable operation of sensitive equipment like solar inverters.

V0 flame-retardant PA6 shell (IP20), works in -40℃~+80℃ and ≤95% humidity for durable indoor use.

35mm DIN rail mounting, 2.5mm²-32mm² wiring support, and LED status indicator for easy installation & maintenance.

● Complies with IEC 61643-11 (T1/T2 type), ideal for industrial, commercial and new energy solar power scenarios.

Product Features
1.Module pluggable and anti vibration design
2.Built-in ultra-low temperature release mechanism
3.Equipped with visual windows and remote signaling contacts
