When Safety Meets Precision
In the EV charging station of a Shenzhen tech park, 32 RT302-00 fuses quietly protected $4.8M worth of equipment during a sudden voltage surge last June. This 100A DC fuse from Sinofuse demonstrates why it’s becoming the #1 choice for 80V DC systems across Asia-Pacific.
EV Revolution’s Voltage Watchdog
Dongfeng Motor’s 2023 test data reveals: RT302-00 achieved 98.7% faster fault interruption than conventional fuses in 40°C battery pack simulations. Its ceramic sand-filled construction enables stable operation through 15,000+ thermal cycles – crucial for EVs facing extreme temperature fluctuations.
Solar Farms’ Dark Horse Protector
At Zhejiang’s 200MW photovoltaic plant, 6,240 RT302 units reduced fuse replacement frequency by 83% compared to previous models. The 25kA breaking capacity proved vital during monsoon season lightning strikes, preventing cascade failures across inverter arrays.
Engineering Reality Check
- 3.2ms average arc extinction time (TÜV certified)
- Withstands 80VDC continuous operation at 100% load
- 50% smaller footprint vs. comparable IEC 60269-6 fuses
As Huawei’s energy storage team lead commented: ‘We switched to RT302 series after it demonstrated zero nuisance tripping in 18-month field trials.’
