Application

JEC Metal Oxide Varistors are ideal for use in power supplies, power systems, line voltage, telecommunication systems, white goods and household appliances.

FAQ
Do varistors have positive and negative poles?
Varistors are not polarized.
The varistor is generally used in parallel in the circuit. When the voltage across the resistor changes sharply, the short circuit of the resistor will fuse the current fuse and play a protective role.

What does the varistor in the motor do?
The main function of the varistor located in the motor is overvoltage protection, that is, the function of disconnecting or cutting off the power supply when the rated voltage is exceeded, and it is not an ordinary varistor, but a high-energy varistor. The nominal voltage is the twice the rated voltage of the motor.
