These voltage surges, also called transient overvoltages, can be caused by a variety of factors, such as atmospheric discharges (lightning), maneuvers in the electrical grid, switching of heavy loads, among others. They pose a threat to sensitive devices such as computers, televisions, electronic appliances, and automation systems.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe main function of a surge suppressor is to detect these voltage peaks and divert the high-intensity transient current to the ground, preventing it from reaching connected devices. This helps protect sensitive equipment from damage caused by overvoltages, which can result in malfunction or permanent failure.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 24px; white-space-collapse: preserve; word-break: break-word; color: #e3e3e3; font-family: 'Google Sans', 'Helvetica Neue', sans-serif; font-size: 16px; background-color: #131314;\" data-sourcepos=\"1:1-1:221\"\u003eThe SIEMENS 3TX4490 3R surge suppressor element is an electrical device used to protect electrical equipment against voltage surges.
