Features Designed for 200kA Circuits: This arrester effectively protects electrical circuits with impulse current capacities up to 200kA, ensuring reliable performance in demanding conditions Advanced Surge Management: Absorbs, consumes, or discharges surge current energy, significantly limiting transient overvoltage and safeguarding your valuable electronic devices Versatile Overvoltage Conversion: Capable of converting higher overvoltage categories to lower ones, providing enhanced protection for sensitive electrical components in your home Features: 1、For Less Than 200kA Electrical Circuit: The arrester module(surge protector) is mainly suitable for 50Hz(or 60HZ) impulse current capacity not greater than 200kA in the electrical circuit 2、Absorb, Consume or Discharge Surge Current: Limit transient overvoltage amplitude, absorb, consume or discharge surge current energy 3、Convert to Lower Overvoltage Category: In the case of a higher overvoltage category, the electrical components to be protected can be converted from one overvoltage category to another lower overvoltage category 4、Electrical Appliances Protection: Suitable for the protection of electrical appliances in households and similar places when there is an induced overvoltage in the line, and when operating overvoltage occurs 5、TH35mm Wide Rail Installation: Installation method is matched with TH35mm wide rail, easy to install and use Specification: Item Type: Surge Protective Devices Product Model: BEM-LY40 Product Specification: 4P40KA Rated Voltage: 220V/380V Maximum Sustainable Working Voltage: 385V Maximum Discharge Current: 40KA Nominal Discharge Current: 20KA Voltage Protection Level: ≤1.8KV Response Time: ≤25nS Ambient Temperature: -40℃~+80℃ Altitude: Not more than 2000meter Relative Humidity: Not more than 90%(25℃) Package List: 1 x Surge Protective Devices Note: betweendiv>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.between/div>betweendiv>2. The surge protector can be equipped with (FS) remote remote signal alarm. The remote signal has one normally open and one normally closed. If one or more modules of the surge protector fail, the will be closed and a fault alarm signal will be sent. Indicates that the module is faulty and must be replaced.bet Package List 1 x Surge Protective Devices
