EPEPRO EP‑40 2P 500VDC Surge Protection Device, 20‑40kA Type‑2 DIN Rail DC Surge Arrester for Solar PV Systems

About this item

1. Reliable DC Surge & Lightning Protection Effectively absorbs lightning surge and transient over‑voltage, protects solar inverters and DC equipment from surge damage for PV power systems.
2. 500V DC PV‑Specialized Design Optimized for 500V DC photovoltaic circuits. 20kA nominal discharge current and 40kA maximum discharge current deliver stable surge‑suppression performance.
3. Visual Failure Indication Window Clear status window for real‑time module condition monitoring. Replaceable plug‑in modules; no need to remove the whole base once modules fail, simple and low‑cost maintenance.
4. DIN Rail Easy Installation Standard 35mm DIN‑rail structure, quick mounting inside PV combiner boxes and distribution cabinets. Flame‑retardant PBT housing improves safety and service life.
5. Wide Application Compatibility Perfect for on‑grid & off‑grid solar systems, PV combiner boxes and battery energy storage systems. Can be matched with DC MCB to build a complete DC protection solution.
