The Bussmann 170M4258 fuse is a high-performance circuit protection device trusted by engineers across industries. Designed for demanding environments, this 500VAC/250VDC current-limiting fuse offers exceptional short-circuit protection with a 200kA interrupting rating. Its compact 10x38mm size makes it ideal for space-constrained applications like solar inverters and EV charging stations. In renewable energy systems, the 170M4258 protects photovoltaic arrays from arc faults – a critical safety feature as solar installations grow 35% annually (SP Global 2023 data). Automotive manufacturers particularly value its fast-acting response time (under 1ms) for battery management systems in electric vehicles. A recent case study showed a 40% reduction in warranty claims for a EV charger manufacturer after implementing these fuses in their DC fast-charging stations. Unlike generic fuses, the 170M4258 maintains stable performance across -50°C to 125°C temperatures, crucial for industrial motor drives in metal processing plants. When selecting circuit protection, engineers should prioritize its UL/CSA/IEC certifications and silver-sand arc quenching technology – features that explain its 99.8% reliability rating in third-party testing. For OEMs upgrading legacy systems, the fuse’s rejection clip design enables backward compatibility with existing panels.
