Features APPLICATION: Mainly applied in 50Hz (or 60HZ) electrical circuit with an impulse current capacity less than 200kA. SURGE ARRESTER: Can limit the amplitude of transient overvoltage as well as absorbing, consuming and discharging the energy of surge current. CIRCUIT PROTECTION: The protected electrical components under higher overvoltage category can be converted from one overvoltage category to another lower overvoltage category. PRACTICAL USING: Designed for the protection of electrical appliances in households and similar places when there is an induced lightning overvoltage in the line, and when the operating overvoltage occurs. CONVENIENT INSTALLATION: Matched with TH35mm wide rail, the installation is very easy to complete with compact size and light weight. Specification: Item Type: Surge Protective Device Product Model: BEM-LY60 Product Specifications: 4P60KA Rated Voltage: 220V, 380V Maximum Sustainable Working Voltage: 385V Maximum Discharge Current: 60KA Nominal Discharge Current: 30KA Voltage Protection Level: ≤2.0KV Response Time: ≤25nS Ambient Temperature: -40℃~+80℃ Altitude: not more than 2000 meters (Approx. 2000m / 6561.7ft). Relative Humidity: Not more than 90% (25℃).  Package List:1 x Surge Protective Device Note:1. The indicator window of the module is green (normal). When the module deteriorates, the indicator window turns red and must be replaced in time;2. The surge protector can be equipped with (FS) remote signal alarm. The remote signal contact has one normally open and one normally closed. If one or multiple modules of the surge protector fail, the contact will be closed and a fault alarm signal will be sent, indicating that the module is faulty and must be replaced.3. Frequently check the air switch or fuse connected in series on the line. Package List 1 x Surge Protective Device
