High interrupt rating provides robust protection against severe short circuits, reducing the risk of equipment damage and downtime; the business impact is improved system reliability and lower maintenance costs in solar deployments. The 355 A current rating at up to 1500 V DC enables efficient protection for large PV inverters and string configurations, translating to safer startups and simplified wiring with bolted blade connections. The 100 kAIC interrupt capability offers resilience against prospective fault currents, supporting compliance with industry standards and reducing the likelihood of cascading failures in arrays. Low watt losses (59 W) minimize heat buildup and energy waste, improving overall efficiency in PV stations. The 3L, non-indicating design with blade fittings simplifies installation and service, enabling faster field replacements and reduced labor costs. Certifications (IEC 60269, UL Listed, CSA Certified) ensure global acceptance, while CE Marked RoHS compliance supports environmentally responsible procurement and end-user safety. This fuse is compatible with PV inverters, array combiners, and disconnects, delivering reliable protection without adding wiring complexity in modern solar microgrids.
