600V 2P DC Surge Protective Device — Professional Manufacturer With OEM/ODM, Bulk Supply & Wholesale Service
The 600V 2P DC surge protective device is specifically designed for residential and commercial photovoltaic systems, DC distribution panels, small to mid-scale energy-storage units, and various low-to-medium voltage DC power networks. As a professional manufacturer, factory, and global supplier, we produce this surge protector using high-quality MOV (Metal Oxide Varistor) components, delivering fast reaction time and stable clamping performance for 600V DC circuits. Our factory supports OEM, ODM, wholesale distribution, and bulk buy orders, offering reliable production capacity and flexible customization for international clients.
This 2-pole SPD is ideal for protecting the positive and negative poles of 600V solar strings, DC controller inputs, combiner boxes, charging modules, and residential PV inverter DC inputs. It provides efficient suppression of transient overvoltage caused by lightning, switching surges, and system disturbances. Each device is manufactured in strict accordance with IEC 61643-31:2018, ensuring conformity with global technical and safety standards for DC surge protection. The product is certified by both CE und TUV, making it fully compliant for export to Europe, Asia, South America, and other regulated markets.
The protective enclosure is made from durable PBT flame-retardant engineering plastic, chosen for its excellent electrical insulation, high mechanical strength, and resistance to heat and environmental aging. This enables the SPD to maintain stable performance even under harsh outdoor solar conditions such as high temperature, humidity, and prolonged UV exposure. The internal MOV array is optimized to achieve consistent surge absorption and low residual voltage, providing reliable long-term protection for connected DC equipment.
Equipped with an integrated thermal disconnection mechanism, the device will automatically isolate the MOV elements once they reach end-of-life or experience excessive stress, preventing overheating and ensuring system safety. A front-mounted status indicator window provides a clear visual signal of working condition, allowing installers and maintenance staff to identify module status without disassembly.
The device supports quick and secure 35mm DIN-rail mounting, making it easy to integrate into PV combiner boxes, DC distribution cabinets, telecom DC power racks, battery-charging stations, and other low-voltage DC applications. Its compact and standardized design fits seamlessly into most DC system layouts.
As a leading manufacturer and SPD factory, we offer strong OEM/ODM capabilities such as private-label branding, customer logo printing, special shell colors, customized surge capacity, and tailored packaging for distributors. With automated production lines and full inspection procedures, we ensure consistent quality, stable clamping voltage, and reliable surge endurance across all units produced.
For wholesalers, EPC contractors, and electrical integrators seeking high-quality 600V DC surge protectors with certified performance and reliable bulk supply, this product offers an ideal combination of durability, efficiency, and manufacturer-direct pricing.
