Product Description 1. Spring-loaded design for easy installation, can be fixed on DIN rail 2. PBT flame-retardant housing, made from safe flame-retardant PBT material, effectively prevents fire risks 3. Modular plug-in design: housing can be replaced without power interruption, maintenance is simple and convenient, base can be reused to reduce maintenance costs 4. With visual window, display shows green when functioning normally and red when faulty and needs replacement 5. When power grid is struck by lightning, it can achieve low resistance within nanoseconds and limit voltage to the specified protection level Product Type: Overvoltage Protection Material: PBT, copper Application: Solar power distribution, power stations, computer room monitoring, also commonly used in paper manufacturing, chemical industry, water supply, municipal administration, food, cement, chemicals, printing and coloring, metallurgy, mining operations, plastic machinery and other electrical rotating and automation control areas in secondary protection waves Nominal Voltage: 385VAC Response Time: <25ns Test Level: Level Ⅱ Protection Class: IP20 Operating Environment: -40℃~+85℃ Cable Specification: Live and neutral conductor: 2.5~35 Earth Conductor: 4.0~35 Signal Line: 1.5 Installation Method: DIN rail installation Product Structure: Plug-in Connection Method: Tunnel Pressing Size: Approximately 91mm / 3.6in 73mm / 2.9in 50mm / 2in 45mm / 1.8in 61mm / 2.4in Impulse Current (Iimp) Nominal Current (In) Voltage Protection Level (kV) 20KA 10KA ≤1.5kV 40KA 20KA ≤1.8kV 60KA 30KA ≤2.0kV
