EARU DC12V-10-20KA Photovoltaic DC SPD Features and Surge Protection Specifications
The EARU DC12V photovoltaic surge protector supports three voltage standards—12V, 24V, and 48V—covering the full range of modern solar DC circuits used in off-grid and grid-tied installations. Three surge rating tiers (10KA–20KA, 20KA–40KA, and 40KA–60KA) let installers match protection to system exposure and lightning risk zones, ensuring no undersized protection degrades system longevity. Dual pole (2P) and triple pole (3P) configurations adapt to single-string or multi-string array designs common in residential and commercial photovoltaic deployments. DIN-rail mounting integrates seamlessly into existing electrical cabinets and combiner boxes, eliminating custom fabrication and installation time. Status indicators confirm suppression events and device integrity, giving electricians and system operators real-time visibility into protection status.
Why Electricians and Solar Installers Rely on Professional Grade Lightning Defense
Direct lightning strikes and induced surges cause catastrophic failures in PV equipment costing thousands in replacement modules, inverters, and labor—this DC protection device intercepts those transient voltage spikes before they reach sensitive electronics. Independent testing confirms the multi-voltage DC protection maintains performance across temperature extremes (–40°C to +70°C) and delivers repeatable clamping action through thousands of surge events without degradation. The selectable surge ratings mean you buy exactly the protection your system needs rather than overpaying for excessive capacity or risking undersized margins. EARU’s DIN-rail SPD integrates with circuit breakers, contactors, and energy meters from the same trusted manufacturer, simplifying procurement and warranty management across your entire electrical distribution. Purchase the lightning protection solution from the official store and protect your solar investment with confidence and competitive pricing.

Thank you!!!!

What confuses me is that no matter what current you buy, all are Up=220V. That doesn’t happen. A 10kA ZIP should have a lower operating voltage than a 30kA one.
I don’t even know what to think. Checked with a high-voltage resistance meter. At 500V the resistance is more than 1 Gigohm, at 1 kilovolt the remaining voltage is 600 V with a surplus.
