I want to know what brands everyone uses?
The function of a surge absorber is to prevent equipment from being damaged by sudden high voltages. The principle involves using varistors for sampling. Varistors typically exhibit high impedance, but they conduct current when sudden surge voltages occur, thereby absorbing those harmful pulse voltages and protecting the equipment. Schneider, ABB, Japanese BL, Phoenix, etc. are commonly used
