Our mini size 40kA 2P GDT AC surge protective device is engineered for applications that require compact construction and high surge discharge capability. As a professional manufacturer, factory, and OEM/ODM supplier, we provide wholesale and bulk buy / in bulk solutions to global clients in the AC power protection industry. This model uses a high-performance gas discharge tube (GDT) filled with non-active Ne (neon) gas, delivering extremely fast response time and stable performance under lightning or switching surges. Unlike MOV-only structures, GDT protection offers higher insulation resistance and lower leakage current, making it ideal for sensitive equipment, small control panels, and space-limited power distribution boxes.
The enclosure is made of PVC/PA66/PBT, offering excellent electrical insulation, heat resistance, and mechanical durability. It is designed for 35mm DIN-rail installation, making the device suitable for modular power systems, automation cabinets, and compact distribution units. The 40kA surge capacity ensures reliable protection for residential, commercial, and industrial AC systems. Each unit is built strictly according to IEC 61643-11:2011 / EN 61643-11:2022, and is certified by CE & TUV, ensuring safe operation and long-term reliability.
