The Aerion Photovoltaic Fuse Series is purpose-built for the protection of modern solar power systems, ensuring safe and reliable operation of PV strings, arrays, and DC circuits. Designed specifically to handle the unique demands of solar energy applications—such as fluctuating DC currents and high ambient temperatures—these fuses safeguard critical components like PV modules, combiner boxes, and inverters against overcurrent and short-circuit faults. Constructed using high-performance fuse elements and temperature-resistant materials, the Aerion PV Fuse delivers rapid fault response while maintaining stable performance over long operating cycles. Its compact, low-power-loss design makes it ideal for high-density installations in both rooftop and utility-scale systems. Key Features Every Aerion PV Fuse is engineered for precision protection and long-term reliability. The fuse link and body materials are selected to withstand elevated DC voltages up to 1500 V, with consistent arc suppression and minimal energy let-through. The fast-acting blow characteristic ensures immediate disconnection under fault conditions, preventing damage to sensitive electronic components. Designed for ease of integration, these fuses are available in multiple sizes and configurations—ranging from 10×38 mm cylindrical types to NH and square-body designs—to accommodate diverse PV system architectures. The components meet global photovoltaic safety standards, offering dependable performance even under harsh temperature variations and continuous solar exposure. Applications The Aerion Photovoltaic Fuse provides dependable circuit protection across a wide range of solar installations, including: PV string and array protection in rooftop systems DC combiner boxes and junction boxes Central and string inverter input protection Battery banks and hybrid energy storage systems Utility-scale and off-grid solar farms Specifications Parameter Specification Rated Voltage 1000 V DC / 1500 V DC Rated Current 1 A – 30 A (10×38 mm type); up to 250 A (NH type) Fuse Type Cylindrical / NH / Square-body Breaking Capacity ≥ 20 kA DC Time-Current Characteristics Fast-acting (gPV class) Operating Temperature Range –40°C to +90°C Power Loss Low power dissipation design Material Composition Silver fuse element, high-strength ceramic body Mounting Options In-line fuse holder, DIN rail fuse base, or panel-mounted Compliance Standards IEC 60269-6 / UL 2579 / EN 60269-6 Certifications CE, TUV, RoHS Typical Applications PV string, combiner, and inverter input protection Performance & Safety Benefits By providing fast and accurate overcurrent protection, the Aerion Photovoltaic Fuse helps extend the service life of PV system components and reduce downtime caused by electrical faults.
