Features Rapid Surge Overvoltage Protection: Our surge protection device opens within nanoseconds to divert surge overvoltage away from electrical devices, ensuring swift and reliable protection during thunderstorms and power surges. Insulated Terminal for Safe Hot Line Operation: Featuring plug-in design and insulated terminals, our surge protection device supports safe hot line operation with rapid response time and strong load-bearing capacity. Working Status Indication Window: Equipped with a working status indication window, our surge protection device provides clear visual feedback - green for normal operation and red for fault indication, ensuring easy monitoring. Fireproof and Corrosion Resistant: Built with fireproof and corrosion-resistant materials, our surge protection device guarantees stability and effective response to working conditions, enhancing safety and longevity. Durable PC Material Construction: Crafted from flame-retardant PC material, our surge protection device offers easy installation through guide rails, ensuring simplicity and reliability in safeguarding your electrical equipment. Specification: Item Type: Surge Protection Device Color: White Material: PC Maximum Discharge Current: 60KA Nominal Discharge Current: 30KA Protection Level: 2.0KV Shielding Grade: IP20 Response Time: ≤25ns Maximum Wire Diameter: 35 hard wire or multi strand wire(mm²) Recommended Wire Connections: 4-25(mm²) Installation Method: 35mm electrical rail mounting Ambient Temperature: -40℃ to +80℃ Main Structure and Operating Principle: In the three phase four wire system, three phase lines and a neutral wire to ground are connected between the protector. Under normal circumstances, the protector is in a high resistance state, when the power grid due to thunder or other reasons out of the reason surge overvoltage, the protector will be immediately in the nanosecond time quickly conductive, the voltage overvoltage into the earth, thus protecting the power equipment on the grid. When the surge voltage through the protector, and disappears after the protector revert to a high resistance state, so as not to affect the normal operation of the grid.
