Features Suitable for Electrical Circuits Under 200kA: Designed for circuits with an impulse current capacity not exceeding 200kA, ensuring reliable defence for your electrical system. Efficient Current Management: Limits transient overvoltage amplitude and effectively absorbs, consumes, or discharges current energy to safeguard your appliances and devices. Lower Overvoltage Category Conversion: Converts electrical components from higher to lower overvoltage categories, ensuring optimal defence against overvoltage damage. Household Appliance defence: Ideal for safeguarding household electrical appliances from induced overvoltage and operating overvoltage occurrences, providing peace of mind for your home. Easy TH35mm Wide Rail Installation: Features a convenient installation method matched with TH35mm wide rail, making it simple and practical to set up for immediate use. Features: 1、For Less Than 200kA Electrical Circuit: The arrester module( protector) is mainly suitable for 50Hz(or 60HZ) impulse current capacity not greater than 200kA in the electrical circuit 2、Absorb, Consume or Discharge Current: Limit transient overvoltage amplitude, absorb, consume or discharge 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 defence: Suitable for the defence 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: Protective Devices Product Model: BEM-LY40 Product Specification: 4P40KA Rated Voltage: 220 V/380V Maximum Sustainable Working Voltage: 385V Maximum Discharge Current: 40KA Nominal Discharge Current: 20KA Voltage defence 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 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 protector can be equipped with (FS) remote remote sign alarm. The remote sign touch has one normally open and one normally closed. If one or more modules of the protector fail, the touch will be closed and a fault alarm sign will be sent. Indicates that the module is faulty and must be replaced.bet Package List 1 x Surge Protective Devices
