When Safety Meets Precision
In the buzzing control room of a Shanghai metro project, engineers were troubleshooting sudden power fluctuations last summer. The culprit? A competitor’s fuse that failed to interrupt 38A overload currents. After switching to Zhongrong’s EV325-4GL 40A, the system recorded zero unexpected shutdowns for 6 consecutive months – a testament to its ±1% current accuracy.
Electric Vehicle Revolution’s Hidden MVP
BYD’s latest electric bus fleet in Shenzhen carries an invisible protector. Each vehicle uses 12 EV325-4GL units to safeguard battery management systems. During extreme fast-charging tests, these fuses demonstrated 0.02s breaking speed at 45A overloads – 30% faster than IEC 60269 standards require.
Solar Farms Trust the Numbers
At the Huanghe Hydropower Plant’s 2.2GW solar array, 8,000+ EV325-4GL units monitor DC combiner boxes. Field data shows 99.98% reliability after 3 years of operation in -25°C to 85°C environments. Project manager Li Wei notes: ‘We’ve reduced maintenance costs by ¥240,000 annually since adoption.’
Industrial Grade Durability
- Withstands 100kA breaking capacity
- 5000+ mechanical endurance cycles
- UL/CCC/IEC triple certification
A robotic welding line in Suzhou replaced fuses monthly until using EV325-4GL. Now they achieve 18-month service intervals despite daily 35A~42A fluctuations.
