PDV07-3,81-H-K is a type of contactor device that is commonly used to control the electrical state of a circuit. The device is widely used in various industrial and manufacturing applications. This article aims to discuss the application field and workings of this contactor device in detail.

A contactor device typically consists of two metal contact forms, separated by an insulating material. When a current is passed through one of the contacts, a magnetic field is created that opens or closes the circuit, depending on the direction of the current. The contactor device is highly versatile and can be used to control both AC and DC circuits. The PDV07-3,81-H-K contactor device is one of the most common and reliable contactor devices available.

The most common application for the PDV07-3,81-H-K contactor is in circuit protection. The device can be used to protect a circuit against overloads, surges, and short circuits, and it can also act as a safety switch to disconnect a circuit when necessary. The device can also be used to provide a remote control of a circuit, allowing for the switching of circuits on and off remotely. In motor starters, the device can be used to control the speed of a motor and prevent overloading.

The working principle of the PDV07-3,81-H-K contactor device is relatively simple. An AC or DC current is applied to the contactor, causing a magnetic field to form between the two contacts. The magnetic field attracts the moving armature, which can either open or close the circuit, depending on the direction of the current. Additionally, the contactor is equipped with a coil that magnetizes the contact, allowing the contact to be held either open or closed.

The PDV07-3,81-H-K contactor device is an ideal device for controlling the electrical state of circuits. It is highly reliable and can be used to protect circuits from overloads, surges, and short circuits as well as providing a remote control option. The contactor\'s working principle is also relatively simple, and it can be used to control AC and DC circuits.
