When Solar Panels Meet Thunderstorms: A 80A Hero Story
In 2023, a solar farm in Guangdong survived a direct lightning strike thanks to an unsung hero – the Zhongrong RS308-HB-4G-80A fuse. While 23% of similar installations reported equipment damage that storm season, this facility’s DC combiner boxes remained fully operational, with the 80A-rated fuse clearing the 9.8kA fault current within 2ms.
EV Battery’s Last Line of Defense
Leading EV manufacturer BYD recently conducted extreme testing on their 800V battery packs. During a simulated thermal runaway event, the RS308-HB-4G-80A demonstrated 0.01Ω resistance stability at 125°C ambient temperature, outperforming 3 international competitors in group testing.
Underground Mining’s Oxygen Saver
A lithium mine in Sichuan replaced traditional circuit breakers with Zhongrong’s solution, reducing electrical fire incidents by 67%. The 4G-speed (4000A breaking capacity) protection prevented $2.8M in potential losses during 2022-2023 alone.
With 80A±5% precision protection and 150% overload endurance, this palm-sized component now safeguards over 1.2 million new energy installations worldwide. Next time you charge your Tesla, remember – there’s a Chinese fuse working overtime to keep those electrons flowing safely.
