Eaton PVS250A-3L-B-15 PV Fuses - UL Listed 1500V
Part Number: PVS250A-3L-B-15
Quick Summary
Eaton PVS250A-3L-B-15 PV Fuses protect solar power systems by interrupting fault current in photovoltaic arrays. Engineers often struggle with choosing fuses that withstand 1500 VDC, deliver reliable opening, and fit standard PV hardware. This device is CE marked, RoHS compliant, and UL listed per IEC 60269, providing robust regulatory alignment for global deployments. Its 3L format, built-in side indicator, and compatible blade-on-bolt holders translate to faster installation and reduced field mistakes. For designers, the 250 A rating, 1500 VDC rating, and 100 kAIC interrupt rating simplify risk modeling and system safety margins. The fuse is purpose-built for photovoltaic systems and inverters, with the 3L size and bolt-down compatibility that speeds field installation.
