FAQs
PV-450A-3L-15 is designed to fit the SD3L-S-PV XL fuse base and similar three‑pole PV bases. Its 3L form factor, blade with top indicator, and 75×205 mm envelope simplify field installation and status monitoring, reducing commissioning time. The blade-and-base compatibility ensures consistent protection across string and inverter assemblies while maintaining a compact footprint.
Key ratings include 450 A continuous amperage, 1500 V DC maximum voltage, and a 100 kA interrupt rating (AIC) for robust fault clearance. Its class gPV designation confirms suitability for PV applications, and pre-arc I2T of 412000 supports predictable arcing performance. With 67 W watt losses, it balances protection with efficiency in solar systems.
Yes. The PV-450A-3L-15 is purpose-built for photovoltaic systems and inverters, including grid-tied installations. Its high-speed fuse-link design minimizes fault energy, protecting DC circuits from string faults, module failures, and inverter faults. The 1500 Vdc rating accommodates modern PV arrays, while the gPV class and RoHS/CE compliance meet common industry requirements.
This fuse carries RoHS conformity and CE marking, along with IEC and UL recognition, aligning with global electrical safety and environmental standards. Compliance supports cross-regional procurement and reduces auditing overhead. Its compatibility with standard PV fuse bases further ensures regulatory alignment during system integration.
Choosing PV-450A-3L-15 enhances uptime by enabling rapid fault isolation thanks to its top-status indicator and fast-acting design. Its 100 kAIC interrupt capacity minimizes catastrophic failures, reducing maintenance costs and service interruptions in solar arrays and inverters. Reliable performance under PV operating conditions translates to lower lifecycle costs and improved system availability.
