The Bussmann 170M1370 fuse is a game-changer in circuit protection, combining precision engineering with rugged reliability. Designed for high-current applications, this 500V-rated fuse supports up to 400A continuous current with an impressive 200kA breaking capacity – enough to handle sudden surges in heavy industrial environments. What sets it apart? The patented ‘sand-filled’ construction enables faster arc extinction compared to standard fuses, reducing downtime by up to 40% in fault conditions according to Eaton’s technical reports. In solar power installations, the 170M1370 has become the go-to solution for protecting PV combiner boxes. A recent project in Arizona’s 50MW solar farm deployed over 2,000 units, where they successfully withstood desert temperature swings from -20°C to 85°C while maintaining stable performance. Electric vehicle charging stations also benefit from its compact design – the 170M1370’s 30mm x 100mm footprint allows easy integration into space-constrained DC fast chargers. Maintenance teams particularly appreciate the visual indicator window that changes color after tripping, a simple but crucial feature that reduces diagnostic time by an average of 15 minutes per incident. For OEMs in the robotics sector, this fuse’s 10ms response time provides critical protection for servo motor drives during overload events. With UL/CSA/IEC certifications and a typical service life exceeding 15 years under normal conditions, the 170M1370 delivers both performance and long-term cost efficiency.
