Terminal blocks, headers, plugs and sockets are essential elements in modern electrical and electronic equipment, as they facilitate faster and easier connections to the electrical circuits of the equipment. The A-TB381-VK10 is a terminal block / connector device especially manufactured for housing the power connection of many industrial single-phase or three-phase appliances. It is mainly used in contactor-capacitor network protection, telecommunications equipment, electrical instruments, etc.

This terminal block consists of two sections. On the one hand, it has the part of the movable contactor, and on the other, there is the port for connecting cables. The movable contactor section has screws whose length, depending on the model, is 12 mm, 6 mm or 4 mm. The cable port can be pressurized with a compression tool, and it has a combined V-knife safety device that prevents the cable from escaping if the tool is not used correctly. This device can support currents of up to 40 A and is designed to ensure an IP20 protection rating.

The working principle of this terminal block can be divided into two parts. First is the contactor section. The movement and connection of the contactor is directly related to the torque generated by tightening the screws. The greater the torque, the greater the stability of the contactor, as well as the better the performance of the contactions. All contactors come with an adjustable nut, which must be tightened enough to hold the wires securely.

The second part is the V-knife port. To connect the cables to this terminal block, the V-knife has to be opened. Once open, the cores of the cables can be inserted into the V-knife to form the connections. After the cables are connected to the V-knife, it must be pressed with a compression tool until the cores are firmly secured within the V-knife. Once the cables are fixed, the V-knife can no longer be opened.

In addition to its contactor and V-knife port, the terminal block also has a set of easily-visible LED indicators per port. The LED indicators indicate whether the connections are established correctly or not. Once the connections are established correctly, the LED indicators will light up, indicating a proper connection.

In summary, the A-TB381-VK10 terminal block is especially manufactured for housing the power connection of many industrial single-phase or three-phase appliances. This device combines a contactor section with a set of screws and a V-knife port to ensure that the connections are properly established. In addition, it has LED indicators for easier monitoring of the connection. Thus, it is an ideal solution for a wide range of electrical and electronic equipment.
