JUU gPV fuse is designed for use in DC circuits where fast and reliable fault protection is required. It is suitable for common DC operating voltages in photovoltaic and energy storage systems, such as DC 250V, 500V, 750V, and up to 1000V, depending on the fuse type and application.The fuse supports a wide range of rated currents, typically from 1A to 400A or higher, allowing flexible selection for different DC circuit capacities. It provides effective protection against overcurrent and short-circuit conditions, ensuring safe disconnection of faulty circuits.DC fuses are available in various construction types and sizes, such as cylindrical fuses and fuse links for holders or fuse bases, making them suitable for different installation requirements. Depending on the application, fuses may feature different breaking capacities, commonly ranging from 10kA to 50kA, ensuring safe interruption of high DC fault currents.Designed for reliable operation in DC environments, the DC fuse offers stable performance and low power loss under normal operating conditions. It is typically used together with DC fuse holders, DC isolator switches, or DC circuit breakers to form a complete protection solution. DC fuses are widely installed in PV combiner boxes, battery systems, and DC distribution panels where fast fault protection is essential.
