Three Phase Surge Protective Device

F series Type 1 surge protectors are designed to be installed where a direct lightning strike risk is high, especially when the building is equipped with an external lightning protection system (LPS or lightning rod). In this situation, IEC and GB standards require the Class I test to be applied to surge, protector, this test is characterized by the injection of 10/350 µs impulse current in order to simulate the direct lightning strike consequence. Therefore these Type 1 surge protectors must be especially powerful to conduct this high energy impulse current. Main Features★ Up: 2.4 kV on 1.2/50 μs voltage impulse★ limp: 15KA on 10/350 µs current impulse★ Internal disconnection, status indicator, and remote signaling★ 35mm electrical din rail mounted Technical parameter The working principle of product    The lightning arrester can effectively protect the power equipment. Once the abnormal voltage appears, the lightning arrester will play a protective role. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect
