Varistor Module 20K 460V 750V 1000V 25K 1000V

The varistor module utilizes the nonlinear characteristics of the varistor. Under normal voltage, it maintains a high resistance state with minimal impact on the circuit. When overvoltage occurs, its resistance drops rapidly, diverting or absorbing the overvoltage energy to protect other components in the circuit. It features fast response and high energy tolerance, making it widely used in power protection, lightning protection, and surge suppression scenarios.
