20D561K MOV Varistor

20D561K MOV varistor (560V), also known as VDR-20D561K, is designed to protect AC power circuits and industrial electronic equipment against transient overvoltage. It responds quickly to surge events and helps limit excessive voltage before sensitive components are damaged. Also known as: 20D561

This model is commonly used in AC input stages, industrial power systems, electrical control equipment and power distribution circuits where stable surge protection and higher energy capability are required.

With a 20mm disc structure, it offers stronger surge current capability and better energy absorption than smaller disc sizes, making it suitable for heavier transient conditions.
