10201 XL PV fuses
High-speed PV fuse-link with a 355 A rating and 1000 Vdc limits fault energy in PV strings, reducing module and inverter damage and enabling shorter downtime during faults. In solar array combiners and disconnects, this fast response translates to higher overall system availability and lower maintenance costs. The 2XL size, blade-with-bolt-hole design, and bolted connection simplify secure mounting in existing enclosures, promoting faster installation with fewer field modifications. The centre fuse status indicator provides at-a-glance health monitoring, cutting time spent on routine checks and lowering maintenance overhead. Compliance with UL, IEC, and CSA standards, plus CE RoHS, supports global deployment and simplifies regulatory audits. A robust 33 kAIC interrupt rating and 26000 I2T pre-arc performance address high fault currents typical in utility-scale installations, enhancing protective margins while keeping arc energy in check. Overall, the PV-355A-2XL-B offers reliable protection with predictable, repeatable performance in a compact footprint.
