Eaton PV-4A10F Photovoltaic Fuses - 50 kAIC UL Listed
Part Number: PV-4A10F
Quick Summary
PV-4A10F photovoltaic fuses protect solar power systems by interrupting fault currents in 1000 V DC PV strings. Engineers often struggle with reliable overcurrent protection for high-voltage PV arrays in tight installation spaces. This device is UL Listed, IEC Rated, and CE marked, aligning with global safety, performance, and environmental compliance. The 10x38 mm ferrule-end design eases field wiring in inverters, combiner boxes, and PV harnesses, delivering fast response (1–3 ms) and low watt losses while sustaining a 50 kAIC interrupt rating. Standardization on these fuses reduces maintenance downtime and expedites certification documentation, delivering lower lifecycle costs and safer, more dependable PV installations across commercial and utility-scale projects.
