0070.4061.B1 Application Field and Working Principle

Varistors, also known as voltage-dependent resistors (VDRs), are nonlinear variable resistors with wide voltage ranges. They are commonly used as electrical protection devices, and they differ from standard resistors due to their characteristic of nonlinear resistive behavior in relation to voltage. This nonlinear characteristic is what makes them useful for protection against high-voltage surges.

One type of varistor is the Metal-Oxide Varistor (MOV). This type of varistor is constructed of metal oxide ceramic material. It is made up of two distinct layers—an inert ceramic layer and a metallic layer containing the active electrons. When voltage is applied, the oxide in the ceramic layer breaks down and ionizes, and the metallic layer becomes a single layer containing positive ions. This layer then changes its resistance and becomes more conductive. As the voltage increases, the resistance decreases, allowing for a greater current.

MOVs are designed to protect electronic components from overvoltage transients (electrical pulses) and are typically used in power lines, telecom equipment, and personal computers. They are also used in surge protection devices (SPDs), thyristor surge suppression arrays, and overcharge protection circuits.

The 0070.4061.B1 is a surge protection device containing several metal oxide varistors. This device is designed to limit electrical surges and transient voltages in automotive, telecom, and power applications. It is made up of a series of metal oxide varistors connected in a chain. These varistors are connected in such a way that the first varistor in the chain takes the most damage, and then subsequent varistors take more damage as the chain progresses. This allows the device to dissipate the most amount of energy before any of the varistors give out, providing maximum protection for the equipment.

The 0070.4061.B1 is designed to protect the equipment it is attached to from dangerous surges. It is able to absorb up to 150 Joules of energy per unit before any of the varistors fail, which gives it a significantly longer service life than other surge protection devices. This makes it particularly useful in high-risk industries, such as oil and gas, where electrical surges can cause thousands of dollars in damage or even cause fatal injury.

In summary, the 0070.4061.B1 is a surge protection device that is made up of several metal oxide varistors and is designed to limit electrical surges and transients in automotive, telecom, and power applications. It is able to absorb up to 150 Joules of energy per unit before any of the varistors fail, making it particularly useful in high-risk industries.
