TVS - Varistors, MOVs, are surge protectors used to divert potentially damaging electrical energy away from sensitive circuitry, due to lightning or line surge events. The MOV-20D820K is one such surge protector and it is suitable for a wide range of industrial applications. This article will discuss the MOV-20D820K in more detail, exploring its application field and working principle.

Application Field

The MOV-20D820K is an AC operated VDR, which is suitable for leakage current detection applications. It is designed for use in finding hazardous ground faults in low-voltage ac power distributions, and thus it is popular in hospital, industrial, IT and other professional settings as a reliable surge protection device. Its wide range of features makes it a very practical device for many different situations.

Working Principle

The MOV-20D820K has a metal oxide varistor (MOV) at its core. This is a voltage-dependent resistor that is composed of two electrodes that are separated by a layer of insulating material. When a surge or overvoltage occurs, the MOV’s resistance decreases, and thus the device diverts the overvoltage away from sensitive components and circuitry, acting as a protective layer. The MOV-20D820K has a high pulse power handling capability, with a peak let-through rating of 20kA, which makes it suitable for a wide range of applications.

The MOV-20D820K has a thermal cut-off capability that will cause it to disconnect in the event of excessive flow of current. This helps to protect the system from any potentially hazardous electrical events that may cause damage. The device also has a LED indicator, so that users can monitor the status of the protection and easily identify any problems that may arise with the surge protector.

The MOV-20D820K provides excellent surge protection and is easy to install. It is small and cost effective, making it an ideal choice for many different applications. The protection it offers makes it an invaluable tool for protecting sensitive circuitry, and its versatility ensures that it can be used in a variety of different environments.

In conclusion, the MOV-20D820K is an excellent surge protector that is suitable for many different applications. It offers excellent surge protection, cost efficiency and easy installation. The device’s metal oxide varistor core and thermal cut-off capability provide reliable protection against hazardous overvoltage events, and its LED status indicator makes it easy to monitor and identify any potential problems. The MOV-20D820K is a great choice for anyone looking for reliable surge protection.
