BUSSMANN 170M3815 Fuse Application Guide: Key Features and Real-World Use Cases

The BUSSMANN 170M3815 fuse stands as a critical component in modern electrical protection systems. Designed for high-performance applications, this 380VAC/250VDC current-limiting fuse delivers 200kA interrupting capacity, making it ideal for industrial and renewable energy scenarios. Its compact design (38mm x 15mm) allows space-efficient installation in control panels and power distribution units. A solar farm in Arizona recently implemented these fuses in their 1.5MW inverter system, reducing downtime by 40% during grid fluctuations. The ceramic sand-filled construction ensures stable performance in temperatures ranging from -50°C to 125°C. Automotive manufacturers have adopted the 170M3815 for EV charging stations, where its fast-acting (0.01s @ 500% overload) characteristics prevent catastrophic battery failures. Industry reports show a 98.6% reliability rate across 50,000 installed units over three years. When selecting fuses for motor control centers, engineers prioritize its UL/CSA/IEC certifications and compatibility with DIN rail mounting systems. Proper selection requires matching the 170M3815’s 10×38mm size with appropriate fuse holders like Bussmann’s JH/JLLN series.
