Compact DC surge protector for solar and DC power systems Key benefits Protects DC equipment from transient overvoltage events by diverting surge energy away from sensitive components. Reduces risk of damage to inverters, combiner boxes, charge controllers, and DC distribution lines, helping minimize and replacement needs. Simple DIN rail installation and two pole design make it easy to integrate into existing solar and DC power panels. Product highlights Type: DC SPD 2P surge protector, designed for DC power applications. Voltage options: 500V, 600V, 800V, 1000V nominal DC systems. Discharge capacity: available in the 40KA to 60KA range; size 60KA specified. Model/Color reference: DC800V. Mounting: DIN rail compatible for fast installation in standard electrical enclosures. Intended use: outdoor power protection for solar installations and other DC power systems. Performance and compatibility Two pole protection for positive and negative DC conductors in single string or combiner box applications. Wide voltage range supports most common PV array and DC power system voltages up to 1000V. Rated discharge current range of 40KA to 60KA handles large transient surges from lightninginduced or switching events, depending on model selection. Practical use scenarios Rooftop solar combiner box: Install the 2P DC SPD at the combiner box to protect downstream inverters and DC wiring from surge events. Groundmounted solar farm: Use DIN rail mounted SPDs in array junction boxes or subarray enclosures to reduce risk of module and inverter damage during transient overvoltages. DC power cabinets and telecom backup: Protect battery strings, charge controllers, and DC distribution panels in outdoor enclosures where transient protection is required. Installation and operation notes Mount on a standard DIN rail inside a suitably rated enclosure for outdoor installations. Select the SPD model that matches the system nominal DC voltage: 500V, 600V, 800V, or 1000V. Choose the appropriate discharge capacity within the 40KA to 60KA range; size 60KA is available. Ensure correct connection of both DC poles for full two pole protection. What makes this product stand out Specifically designed for DC environments and solar applications, offering two pole protection up to 1000V DC. Available discharge capacity up to 60KA to handle energy transients. DIN rail form factor for straightforward retrofit and installations in standard electrical cabinets.
