    Our mini size 20kA 2P GDT AC surge protective device is specially developed for compact single-phase AC power systems that require effective surge protection with minimal installation space. As a professional manufacturer, factory, and OEM/ODM supplier, we provide this model to global wholesalers and distributors who need reliable AC surge protection solutions for bulk buy, in bulk, and wholesale orders. This SPD uses a high-quality gas discharge tube (GDT) filled with Ne (neon) gas, offering extremely fast response time and exceptional insulation performance. Compared to traditional MOV-only devices, the GDT structure provides lower leakage current, higher stability, and longer operational life, making it ideal for environments with medium surge risk.

    The product is built with a durable PVC/PA66/PBT housing, ensuring high dielectric strength, flame retardancy, and resistance to heat and impact. The 2-pole structure protects L + N lines in single-phase AC networks, suitable for small distribution boxes, automation control panels, building electrical systems, smart home power supplies, UPS systems, and AC outputs of solar inverters or energy storage systems. Its mini size design significantly reduces installation space, making it popular for compact power cabinets and dense rail-mounted configurations.

    Our production follows strict international standards, including IEC 61643-11:2011 / EN 61643-11:2022, and every unit carries CE and TUV certifications, ensuring compliance, durability, and global market acceptance. As a professional manufacturer, we support full OEM and ODM customization, including circuit parameter adjustments, logo printing, private label branding, housing color customization, and packaging design. For global distributors and wholesalers looking for dependable, compact, and factory-direct AC surge protection devices, this mini size 20kA 2P GDT SPD is a highly competitive and reliable choice.

    Applicable scenarios / Application industries

    Engineered for 35mm DIN-rail installation, this device ensures quick mounting, easy maintenance, and compatibility with standard modular power distribution systems. Although compact, it delivers a reliable 20kA surge capacity, providing essential protection against lightning-induced surges and switching transients. This makes it an excellent fit for residential, commercial, and light industrial electrical environments where safety, reliability, and panel space optimization are priorities.
