FAQs
The PVS315A-3L-B-15 is designed for photovoltaic systems up to 1500 V DC and 315 A continuous current. It fits 3L fuse holders with blade or bolt-hole interfaces, making it suitable for PV arrays, inverter mains, and string protection in commercial and utility-scale solar projects. Ensure compatibility with the fuse holder and follow UL/IEC installation guidelines for safe operation.
This fuse is CE Marked and RoHS compliant for EU markets, and UL Listed with IEC 60269 recognition for broader global deployment. These certifications support regulatory acceptance, safety compliance, and streamlined procurement across international solar projects.
Install with the blade-and-bolt compatible fuse holder using the 3L size, ensuring proper alignment with the side indicator for status. Torque requirements should follow the holder’s specification, and confirming the indicator before energizing ensures correct operation and safe maintenance access in PV inverters and string boxes.
The fuse features a 100 kAIC interrupt rating with a pre-arc I2T of 175000, delivering rapid fault interruption and limiting energy transfer during faults. This helps protect PV modules and inverters from damaging overcurrent events while supporting reliable system uptime in solar installations.
Low watt losses of 52 W and a status indicator contribute to reduced energy waste and quicker fault diagnosis, lowering maintenance costs and downtime. The robust 1500 V, 315 A rating supports longer service life in continuous PV protection, delivering a favorable return on investment for solar plant operators and EPCs.
