Modular Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), and they are used in power generation, distribution, and utilization scenarios. In a broad sense, contactors refer to electrical devices used in industrial electricity, where a coil carries current to create a magnetic field, closing the contacts to control electrical loads. Before installing AC … Read more
