When 80V Systems Need Ironclad Protection
In the EV charging station at Shenzhen Bay Tech Park, engineers faced a nightmare scenario last summer: A sudden short circuit in a 72V battery pack caused cascading failures across three charging piles. This incident sparked demand for the Zhongrong RT302-00 – a DC fuse that’s redefining protection in high-voltage environments.
25KA Breaking Capacity in Action
The RT302-00 isn’t your grandpa’s fuse. With 25kA breaking capacity at 80VDC, it’s handled:
- Solar farm arc faults in Xinjiang’s 50°C desert heat
- Robotic arm power surges at Foxconn’s Shenzhen plant
- 48V/72V battery system faults in NIO’s swap stations
Test data from TÜV Rheinland shows 0.01s arc extinction time – 30% faster than IEC 60269 standards require.
400A Continuous Current? No Sweat
At Shanghai’s Lingang Hydrogen Station, 36 RT302-00 units have clocked 12,000+ hours protecting electrolyzer power supplies. Maintenance logs reveal:
| Parameter | Performance |
|---|---|
| Voltage Drop | <0.2V at 400A |
| Temp Rise | 45K @ 150% load |
“These fuses survive where others melt,” says station engineer Zhang Wei.
GS Certification Opens EU Markets
When German e-bike maker Riese & Müller needed certified protection for their 60V/35A motors, the RT302-00’s GS mark smoothed CE compliance. Now protecting 200,000+ premium e-bikes across Europe.
From 5G base stations to electric ferries, this 32.5mm x 10mm powerhouse proves big protection comes in small packages. Next-gen DC systems demand fuses that keep pace – RT302-00 delivers.
