PVS-3L Fuses data sheet
Amperage and voltage ratings provide clear protection boundaries. A 350 A current rating paired with a 1500 V DC rating means the fuse can safely interrupt faults in mid- to large-scale PV arrays without overrating components. In practice, installers specify for solar strings and inverters in utility-scale and commercial installations. High interrupt rating of 100 kAIC ensures rapid fault clearance in high-energy fault scenarios, reducing the risk of equipment damage and fire in utility-scale projects. Pre-arc (I2T) of 250000 enhances reliability during heavy fault currents by minimizing contact erosion and extending fuse life, which translates to lower replacement costs and less downtime. The side indicator and 3L size support straightforward diagnostics and modular mounting, enabling faster commissioning and easier field servicing. Compatibility with blade-with-bolt-hole fuse holders simplifies retrofit and new installs alike, while 54 W watt losses are managed to minimize heat within the switchgear and panels in PV protection schemes. All these features align with industry needs for compliant, efficient PV protection, inverter safety, and long-term system availability.

FAQs
PVS350A-3L-B-15 is suitable for blade with bolt holes fuse holders and uses a 3L bolt-on configuration. The side indicator aids in rapid field diagnostics, and the blade-with-bolt-hole compatibility streamlines retrofits and new installations in existing racks or switchgear.
The fuse provides a 350 A amperage rating, 1500 V DC voltage rating, and a 100 kAIC interrupt rating. These specs mean it can safely interrupt faults in medium to large PV arrays and inverters, meeting common utility-scale and commercial PV protection needs while supporting fast fault clearance.
Yes. With a 1500 VDC rating and 350 A protection, the PVS350A-3L-B-15 is designed for PV inverters and PV strings. Its indicator feature helps technicians verify status quickly, reducing maintenance time during commissioning and fault investigations.
It is CE Marked and RoHS Compliant, with IEC 60269 and UL Listed certifications. These approvals ensure regulatory compliance, safety, and compatibility with international standards, streamlining supplier qualification and reducing risk during procurement.
The 100 kAIC interrupt rating, 250000 pre-arc I2T, and 54 W watt losses contribute to reliable fault interruption with controlled heat generation, reducing nuisance trips and component wear. The side indicator supports quick diagnostics, shortening maintenance windows and improving system availability.
