Surge protective devices, such as V20E250PL2B1, are designed to protect electrical and electronic systems from transient surges or overvoltage. It is classified as a TVS-Varistor, Metal Oxide Varistor (MOV). This type of protection is often used in harsh environments such as railways, power plants and construction sites.

A varistor is an electronic component that is characterized by a voltage-dependent non-linear resistivity. It is mainly used to protect electrical components from high voltage surges, voltage spikes, or other transient overvoltage conditions. TVS-Varistors and MOVs are the two types of varistors commonly used in surge protection devices.

V20E250PL2B1 is a MOV with an operating voltage of 250VAC and a peak pulse current rating of 20KA. This device is made up of zinc oxide element encased in a cylindrical epoxy shell, with nickel-plated copper connecting leads. It also includes a safety varistor that provides additional protection against overvoltage. The device’s maximum surge current is 5KA.

The main purpose of the V20E250PL2B1 is to provide overvoltage protection for circuits and components from transient surges or overvoltage events. This device can also be used to limit voltage surges and reduce the maximum potential effect of an overvoltage event. Overall, the MOV is designed to absorb and dissipate energy, thus preventing damage to connected equipment and components.

The working principle of the V20E250PL2B1 is that during normal operation, the MOV acts as an open circuit and no current passes through it. In the event of an overvoltage event, the MOV starts to conduct and thus divert the excess energy away from the protected components. The MOV also has a safety varistor that helps to further limit the peak voltage and dissipate the excess energy. Once the transient surge has passed, the MOV will return to its open circuit state and the circuit will once again become operational.

The V20E250PL2B1 is widely used in many industrial and commercial applications. It can be used in AC power systems, telecommunications systems, automation systems, audio equipment, computers, and electrical appliances. It is also suitable for use in harsh environments, such as in outdoor and factory areas, where there is a high risk of electrical overvoltage.

In summary, the V20E250PL2B1 is a MOV-based surge protection device that can be used to protect circuits and components from transient surges or overvoltage events. It is an important safety device that helps to reduce the risk of damage caused by overvoltage events and limit the potential effects of these events. The device is suitable for use in a variety of applications and harsh environments, and is a reliable and effective form of overvoltage protection.
