Eaton PV-40ANH1 Photovoltaic Fuse - UL Listed 50 kAIC
Part Number: PV-40ANH1
Quick Summary
PV-40ANH1 photovoltaic fuse from Eaton provides high-speed overcurrent protection for photovoltaic arrays and DC power systems. In solar deployments, selecting an undersized or incompatible fuse can trigger nuisance trips, shorten module life, and complicate fault clearance. This device carries CE marking, RoHS compliance, UL Listed, and IEC/CSA certifications, ensuring regulatory alignment across markets. The NH1 form factor and a dual-status indicator simplify installation and diagnostics, while compatibility with standard fuse bases reduces installation errors and maintenance time, delivering reliable protection with minimal downtime for PV inverters and combiner boxes.
