When Safety Meets High Performance
In the buzzing control room of a new energy vehicle factory, engineers were troubleshooting a mysterious battery pack failure. The culprit? An undersized fuse that couldn’t handle peak currents. This real-world scenario highlights why the Zhongrong RS308-HB-3N 350A has become the dark horse in power protection.
Core Strength in Compact Design
Measuring just 10.3×38.1mm, this micro giant boasts:
• 350A rated current with 1000VDC breaking capacity
• -40°C to 125°C operational range
• 98.7% reliability in extreme condition tests
Three Real-World Heroes
Case 1: For a top EV manufacturer, integrating RS308-HB-3N reduced BMS protection failures by 63% in winter operations.
Case 2: In a 2MWh energy storage system, these fuses successfully interrupted 23kA short-circuit current within 2ms during a thermal runaway event.
Case 3: A charging station operator reported 0 fuse-related downtime in 18 months after switching to this model.
Engineering Breakthroughs
The secret lies in:
• Silver-alloy fusible element with ceramic arc extinguishing
• Patented HB-3N arc control technology
• Military-grade epoxy encapsulation
As the new energy sector grows at 28% CAGR, RS308-HB-3N is becoming the invisible backbone protecting our electrified future. Next time you see an EV silently gliding by, remember – there’s a piece of Zhongrong innovation keeping its heartbeat steady.
