14D681K MOV Varistor

14D681K is a 14mm metal oxide varistor designed to provide robust protection against transient overvoltage in high voltage environments. Its larger disc structure allows higher energy absorption, making it suitable for applications requiring strong surge endurance.

This varistor is typically used in industrial power systems, electrical equipment and high voltage circuits where reliable surge suppression is critical.

With a nominal varistor voltage of 680V, it effectively clamps excessive voltage caused by lightning surges, switching operations and unstable grid conditions, helping to protect electronic components and improve system reliability.
