Features defence: Provides instant defence against overvoltage caused by or other sources, safeguarding electrical equipment from damage. Reliable Working: Insulated terminals ensure quick response and strong defence capabilities, offering reliable and safe . Clear Display: Features a working status indication window, with green indicating normal and red indicating faults, ensuring clear visibility of the device's condition. Fireproof and Corrosion Proof: Constructed with fireproof and corrosion-resistant materials, ensuring stability and effective response to working conditions. Premium Material: Crafted from flame-retardant PC material, offering durability, sturdiness, and ease of installation through guide rails. Features: 1、Device Working Mechanism: When the system has a overvoltage due to thunder or other reasons, the protector immediately opens quickly within nanoseconds and introduces the overvoltage to the earth to provide defence for electrical devices. 2、Insulated Terminal: This defence device is with plug in design, support hot line . Insulated terminals, reliable and safe, rapid response time, strong load bearing capacity. 3、Condition Indication Window: This defence device has a working status indication window, green indicates normal, red indicates fault. 4、Fireproof and Corrosion Proof: Our defence device is fireproof and corrosion resisting and stable, can effectively respond to the working status. 5、Made of PC Material: Our defence device is made of flame retardant PC material with exquisite craftsmanship, easy to use, very simple to install through the guide rails. Specification: Item Type: defence Device Color: White Material: PC Maximum Discharge Current: 60KA Nominal Discharge Current: 30KA defence 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 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 voltage through the protector, and disappears after the Package List 1 x Surge Protection Device
