    TRS3 Surge Protection Device

    TRS3 series modular photovoltaic DC lightning arrester series are widely used in photovoltaic power generation and other power systems, such as various combiner boxes, photovoltaic controllers, inverters, AC and DC cabinets, DC screens and other important and vulnerable to lightning strikes DC equipment. The product integrates isolation and short-circuit devices to ensure safe electrical isolation of the protection module and prevent fire hazards caused by DC arcing. The fault-proof Y-type circuit can prevent the generator circuit insulation failure from causing damage to the surge protection, and can ensure the safe replacement of the protection module without arcing. Protects against indirect lightning or direct lightning effects or other instantaneous overvoltages.
