3 Phase Outdoor Disconnect

This series of 3 phase outdoor disconnect is suitable for distribution lines operating at 50Hz AC and rated voltages up to 500V. They provide short-circuit and overload protection for the low-voltage side of transformers. Under certain conditions, they can switch unloaded transformers, unloaded lines, and rated operating current. They cleverly combine the isolation function of a disconnector with the short-circuit protection of a high-voltage fuse, creating a compact, versatile, and economical combination device. The disconnector itself establishes a clearly visible, safety-compliant disconnect point in the circuit, ensuring reliable isolation from the power source during equipment overhaul or line maintenance, greatly enhancing the safety of electrical operations. Furthermore, because they are designed for outdoor environments, these devices typically feature a high degree of protection (e.g., IP rating). Their housing and insulation components effectively withstand harsh weather conditions such as wind, rain, snow, dust, ultraviolet light, and moisture and salt spray, ensuring long-term operational stability and reliability.
