Eaton PV-400A-3L-B Photovoltaic Fuse - UL Listed

High-speed protection with 400 A rating and 1000 Vdc input is engineered to rapidly interrupt DC faults, minimizing arc energy and protecting PV modules. Business impact: fewer module outages and safer DC wiring; application: PV arrays, inverter inputs, and solar feeders. Bolted blade connections provide robust, vibration-resistant installation suitable for outdoor solar environments, reducing commissioning time and ensuring reliable long-term performance. This fuse’s 3L size and precise 75 x 91 x 205 mm footprint fit standard PV protection schemes, enabling straightforward retrofits and scalable deployments. The top fuse status indicator enables quick status checks from the field, supporting proactive maintenance and faster fault diagnosis. Certifications including CE Mark, UL Listed, and CSA Certified underpin compliance across international solar projects, while RoHS aligns with sustainability goals. Operationally, the device handles 400 A at 1000 Vdc with a 50 kAIC interrupt rating, delivering strong protection for high-energy DC strings and inverters. Watt-loss and pre-arc metrics (82 W, I2T 44000) support engineering calculations for thermal and protection coordination. In practice, this fuse enhances reliability in PV systems, enabling predictable performance, easier audits, and optimized maintenance planning for utility-scale and commercial solar installations.
