Features Rapid defence: With nanosecond speed, our device swiftly opens to divert overvoltage, safeguarding your electrical devices during thunderstorms and other events. Insulated Terminal Design: The plug-in design and insulated terminals enable safe and reliable hot line , with rapid response time and high load bearing capacity. Status Indication Window: The built-in indicator window displays green for normal and red for fault conditions, providing at-a-glance monitoring. Fireproof and Corrosion Resistant: Engineered with fireproof and corrosion-resistant materials, ensuring stable and reliable performance to effectively respond to working status changes. Premium Construction: Crafted from flame-retardant PC material, our device offers simple installation via guide rails, guaranteeing ease of use and durability. 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
