AC surge protective device LY1-C40/1(S)PLUGGABLE SINGLE-POLE SPD,
As a professional AC surge protective device manufacturer, our 40kA 1 pole SPD is designed for single-phase AC power systems.
It adopts high-quality MOV ZnO varistors to provide fast response and strong surge absorption against overvoltage transients.
The device body is made of PVC/PA66/PBT, offering excellent insulation, flame resistance, and durability.
Fully compliant with IEC 61643-11:2011 / EN 61643-11:2022, and certified by CE & TUV.
As an experienced OEM/ODM factory and supplier, we provide wholesale, in bulk, and bulk buy options for global distributors.
Ideal for AC power lines, solar systems, control cabinets, and combiner boxes, and supports 35mm DIN rail installation.
