14D561K MOV Varistor

14D561K is a 14mm metal oxide varistor developed to provide effective protection against transient overvoltage in circuits exposed to medium to high surge conditions. Its larger disc structure enhances energy absorption capability, making it suitable for applications requiring stronger surge endurance.

This varistor is commonly used in power supply systems, industrial electronics and electrical equipment where voltage stability and protection reliability are critical.

Operating at a nominal varistor voltage of 560V, it clamps excessive voltage generated by lightning events, switching operations and power grid fluctuations, helping protect sensitive components and improve system stability.
