Eaton Bussmann - Products for sustainable energy
High-speed interruption delivers immediate fault energy limits, protecting PV modules and cables while reducing thermal stress and potential fire risk in solar arrays. Business impact: lower maintenance costs and increased uptime through faster fault clearing; application: photovoltaic strings in utility-scale and commercial installations. The 32 A, 1300 Vdc rating supports modern PV configurations with long-lived performance in high-voltage DC systems, while the 10 kAIC interrupt rating ensures robust protection during severe fault events. Application note: suitable for IEC/UL-listed Bussmann PV fuse holders; compatibility simplifies retrofits and stock management for procurement teams. Pre-arc (I2T) of 105 and watt losses of 10.4 W balance fast clearing with manageable heat generation, ensuring reliability in constrained enclosures. Class gPV designation provides recognized PV protection performance, aligning with industry standards and reducing design risk. The fuse is non-indicating, which lowers component cost and avoids false indicators in harsh environments. Dimension and form factor (14 x 65 mm) enable quick replacement in standard 14x65 mm fuse blocks, streamlining commissioning and field service.
