1500V 3P DC Surge Protective Device — Professional Manufacturer OEM/ODM Factory
Our 1500V 3P DC surge protective device is engineered for high-voltage photovoltaic and industrial DC applications where stable, long-term surge protection is essential. Using a high-energy MOV (Metal Oxide Varistor) as the core component, this device delivers fast response and strong surge absorption capability for 1500-volt DC power systems. It is designed and manufactured in our professional OEM/ODM surge protective device factory, exported worldwide to solar integrators, EPC contractors, inverter manufacturers, and PV system distributors.
The enclosure of this model is built using high-temperature-resistant PA66, ensuring excellent mechanical strength, UV stability, and heat resistance when installed outdoors in utility-scale solar farms or industrial DC cabinets. The entire product is produced in strict accordance with IEC 61643-31:2018, meeting the requirements of modern photovoltaic protection systems. With both CE certification und TUV testing approval, it provides an internationally reliable protection option for global buyers who need long-term, maintenance-free surge suppression.
As a direct manufacturer and wholesale supplier, we support complete OEM/ODM customization services such as housing color, private label branding, packaging design, and product parameter adjustments. Bulk purchasing (in bulk / wholesale orders) is fully supported with stable supply capacity for long-term projects. Our production line uses automated testing equipment to guarantee response time, leakage current stability, voltage protection level, and thermal trip accuracy.
This 1500V 3P DC surge protective device is an ideal solution for companies looking to improve PV system reliability while reducing maintenance downtime. It is widely used in large-scale solar farms, commercial rooftop installations, off-grid DC stations, energy-storage DC buses, and other high-voltage DC applications. As an experienced SPD manufacturer, we offer competitive pricing, long-life MOV technology, strict quality control, and fast delivery for international customers seeking dependable high-voltage DC surge protection.
Applicable scenarios / Application industries
The 3-pole structure is suitable for 1500V DC arrays, string combiner boxes, central inverters, energy-storage charging cabinets, and large solar plants. Each MOV module is optimized to handle high-energy lightning surges and switching transients that commonly occur in large PV installations. The module features quick-replaceable cartridges, thermal disconnection mechanisms, and clearly visible status indicators so maintenance teams can easily monitor protector condition in the field.
