Our mini size 20kA 4P GDT AC surge protection device is specially designed for compact three-phase AC systems requiring reliable surge suppression at moderate surge levels. As an experienced SPD manufacturer, supplier, and OEM/ODM factory, we support wholesale, bulk buy, and in bulk orders for integrators and distributors worldwide. Utilizing a Neon gas (Ne) GDT, this model provides excellent isolation performance, low residual current, and long service life. The device is ideal for small distribution boxes, HVAC control systems, and compact industrial panels.
The body is made of PVC/PA66/PBT, offering excellent thermal resistance, flame retardancy, and structural strength. The 4-pole configuration protects L1 + L2 + L3 + N, making it suitable for three-phase four-wire networks in commercial and industrial applications. Despite the mini size, it delivers a stable 20kA surge capacity, ideal for systems with moderate surge exposure.
Compliant with IEC 61643-11:2011 / EN 61643-11:2022, and certified with CE & TUV, the device meets international performance and safety standards. As a factory specializing in SPD production, we provide OEM customization for specifications, housing, branding, and packaging.
