Product Overview
Key Product Features
✅ Optimized for 1000Vdc Photovoltaic DC System
Special DC voltage‑withstand design, stable long‑term operation under 1000Vdc PV working voltage, effectively reduce thermal runaway risk.
✅ T2 Surge Capacity: In 20kA, Imax 40kA
Powerful surge‑discharge capacity, reliably suppress lightning‑caused transient over‑voltage on solar DC loops.
✅ 2‑Pole Structure for DC+ and DC‑
Independent protection for positive and negative DC lines, provides complete surge protection for photovoltaic DC circuit.
✅ Plug‑In Modular Replaceable Cartridge
Faulty module can be directly pulled out and replaced without removing base block, simplifies field maintenance and lowers spare‑part cost.
✅ Visual Status Indicator Window
Green window for normal operation; color‑changed window alerts module failure, quick status check without power‑off testing.
✅ Standard 35 mm DIN‑Rail Mounting
Direct fit for standard DIN rail inside solar combiner boxes and distribution cabinets, compact and space‑saving.
✅ Compliant with IEC 61643‑31 Standard
Passes full type test, CE marked, qualified for global 1000V photovoltaic project applications.
