Construction & Working Principle
The ANL/B200SF56 features a robust bolt-down structure that ensures stable electrical connection even under vibration, shock, or high-temperature conditions—critical for automotive and industrial environments. Unlike plug-in fuses, bolt-down design eliminates loose contact risks in high-current circuits.
Inside, a precision-engineered fuse element (silver-plated copper) melts under overload or short circuit, breaking the circuit instantly. The high-grade thermoplastic housing provides excellent arc extinguishing and insulation performance, ensuring safety during fault clearing.
Core Advantages
- Ultra-high current handling: up to 700A, ideal for heavy-duty DC systems
- High interrupting capacity: 6kA safely clears severe short circuits
- Vibration-resistant bolt mounting: no loose contact in trucks/EVs
- Wide voltage coverage: 125V–250V DC, fits most automotive battery systems
- Compact size: 56mm hole distance, easy installation in limited space
- Long lifespan: durable materials resist aging and thermal cycling
Typical Applications
- Electric Vehicles (EV/HEV): main battery protection, high-voltage DC circuits
- Trucks & Heavy Machinery: 24V/48V battery systems, starter circuits
- Solar & Energy Storage: battery bank protection, off-grid DC systems
- Industrial DC Power: UPS, inverters, heavy-duty DC equipment
- Marine & RV: 12V/24V high-current DC distribution
