Waterproof protection: IP66 rated for resistance against rain and dust. A slotted screw with a waterproof seal ensures sealing and longlasting performance in outdoor or damp environments for solar energy systems and motor control applications. conductivity mechanism: Silver contacts copper to deliver enhanced electrical conductivity and reduced resistance, enabling reliable power transmission and efficient switching for 35A threephase circuits in industrial and alternative energy setups. Robust construction: ABS body with dimensions 166 x 83 x 86 mm. This 3pole rotary switch provides exceptional durability and mechanical strength, suitable for heavyduty electrical installations and load isolation requirements. For easy installation: Clear terminal markings and standard mounting provisions simplify wiring and mounting for electricians and DIY enthusiasts working with solar inverters, generators, or motor control panels. Use scenario 1: Outdoor solar energy installation where a rugged, weatherresistant isolator is needed to safely disconnect circuits in sun, rain, or dustprone environments. Use scenario 2: Industrial motor control panel in a workshop or factory with exposure to moisture or dust, requiring reliable isolation and easy maintenance. Use scenario 3: Standby generator or portable power setup in damp or outdoor locations, where secure connection, easy wiring, and durable performance are essential.
