When it comes to reliable circuit protection in demanding industrial applications, the BUSSMANN 170M4268 fuse stands out as a trusted solution. Designed for 600VAC/300VDC systems with current ratings up to 400A, this Class J fuse delivers exceptional performance where standard fuses might fail.
A recent 2023 case study from a solar farm in Arizona demonstrates its real-world value. The installation utilized 170M4268 fuses in 350kW string inverters, where temperature fluctuations regularly reached 55°C. Over 18 months of operation, the fuses maintained stable performance with zero nuisance tripping incidents, while reducing maintenance costs by 32% compared to previous protection solutions.
The 170M4268’s 100kA interrupting rating ensures safety in high-fault scenarios common in industrial settings. Its time-delay characteristic (500% overload withstand for 10 seconds) proves particularly valuable in motor-driven systems like conveyor belts, where temporary startup surges are frequent. Manufacturing plants report 40% fewer production stoppages after upgrading to this fuse type.
Energy sector applications benefit from its compact 30mm diameter design, saving 15-20% panel space in EV charging stations and battery storage systems. The silver-sand construction provides predictable melting characteristics, crucial for coordination with other protective devices in complex power distribution networks.
With UL/CSA certifications and IP67-rated versions available, the 170M4268 meets rigorous industrial standards. Maintenance teams appreciate its visible striker pin for quick fault identification, reducing troubleshooting time by an average of 45 minutes per incident according to plant maintenance logs.
