High-speed PV fuse design delivers rapid fault clearance, reducing arc energy and protecting DC wiring; this translates to safer installations and less panel damage in PV systems. The 1500 Vdc voltage rating supports both rooftop and utility-scale PV configurations, enabling safer protection across diverse DC bus architectures. A robust 100 kAIC interrupt rating paired with Class gPV construction ensures dependable fault isolation even in high-current scenarios, lowering the risk of cascading failures in inverters and combiner boxes. Centre fuse status indicator and side indicator provide immediate visual diagnostics, speeding maintenance and minimizing downtime during inspections or fault events. The bolt-in 3L form factor, coupled with a 201.4 mm length and 91 mm width/height, simplifies retrofit and new-install workflows, reducing installation time and spare parts needs. Watt losses of 59 W and pre-arc I2T of 195000 offer predictable thermal and protection performance for mission-critical solar applications, supporting long-term reliability and compliance with IEC/UL standards.
