AC surge protective device LY1-C40/1(S)+1PLUGGABLE SINGLE-POLE SPD,
This 40kA 1P+N GDT AC surge protective device combines GDT (Gas Discharge Tube) and MOV ZnO technology, providing coordinated surge protection with fast response and low residual voltage.
It’s designed for single-phase + neutral systems, ensuring both line and neutral protection.
The housing uses PVC/PA66/PBT, ensuring strength, insulation, and heat resistance.
Complies with IEC 61643-11:2011 / EN 61643-11:2022, and holds CE & TUV certificates.
We are a professional OEM/ODM manufacturer and factory, providing wholesale, bulk buy, and in bulk solutions for distributors worldwide.
Easily installed via 35mm DIN rail, ideal for solar systems, residential control boxes, and AC surge panels.
