FAQs
The PVS400A-3L-B-15 is designed for blade with bolt hole compatibility and includes a side indicator for quick status checks. Mount it in standard protective enclosures used for PV strings and inverter cabinets, ensuring correct orientation to maintain visibility of the indicator and proper cooling. Verify enclosure dimensions to accommodate the 201.4 mm length and 74 mm width of the device within the 3L form factor.
The fuse is rated for 400 A at 1500 V DC, with a 100 kAIC interrupt rating, Class gPV, and a pre-arc I2T of 315000. These figures mean it can protect PV strings against overcurrents and short-circuits typical in PV arrays and inverters, while handling high short-circuit energies safely and efficiently.
Yes. Its high current capability (400 A), high DC voltage rating (1500 V), robust interrupt rating (100 kAIC), and PV-class designation make it suitable for both utility-scale and commercial rooftop PV systems, providing reliable protection across string configurations and inverter connections.
The PVS400A-3L-B-15 carries CE marking and RoHS compliance, and is UL Listed with IEC 60269 compatibility, aligning with global electrical protection standards and simplifying compliance in diverse markets.
With a side indicator for quick status checks, 3L form factor ease of installation, and robust 66 W watt losses, the device minimizes maintenance time and energy losses. Its high interrupt rating reduces upstream fault propagation, contributing to longer system uptime and a lower total cost of ownership for solar PV projects.
