We are a high-quality 50kA 1P+N GDT AC surge protective device manufacturer, combining GDT (Neon gas) and MOV ZnO components for hybrid protection. As a factory, we provide OEM, wholesale, and bulk buy solutions worldwide.

This SPD offers enhanced insulation resistance and lower residual voltage, making it ideal for smart homes, office buildings, and solar applications. The graphite C enclosure ensures superior flame resistance, while the IP65 design allows safe outdoor installation.

Compatible with 35mm DIN rails, this SPD is CE certified and includes a 2-year warranty.

We supply SPDs in bulk, customized by brand, voltage, or size. Our factory focuses on high-quality, reliable surge protection for AC networks under the OEM model.
