FE01D00400 - CYLINDRICAL FUSE 10X38 GPV 4A

Why Choose the FE01D00400?

Lovato’s FE01D00400 is a dedicated photovoltaic fuse link designed for 10x38mm applications, delivering dependable DC protection at up to 1000 V. Rated at 4 A with a robust 30 kA breaking capacity, it safeguards PV strings and balance-of-system components against overcurrents. Built to the IEC/EN 60269-6 standard, this compact FE series device integrates seamlessly into modern solar installations.

Engineered for reliability in demanding environments, the FE01D00400 operates from -20 to +70 °C and up to 3000 m altitude. The DC-only design suits PV circuits, while its 8 g form factor simplifies handling in fuse carriers sized 10x38mm. With no light indicator to misinterpret, and full IEC compliance, it offers clear, consistent protection across new builds and retrofit solar projects.
