Terminal Blocks - Barrier Blocks
TB400-08 is a kind of wire terminal block products commonly used on electrical circuits. It consists of two parts, the base and connector. The connector is composed of a screw and a contact block, while the base is made of plastic. It is a quick-connect product with excellent performance, widely used in the application of low and medium current circuit connection, such as electronic control and normal signal transmission.

The contact block is a core component of TB400-08, typically consisting of drilled material rammed with several pins. The contact block is connected to the actuator by a screw, which is usually of two types: fastening screw and reversing screw. The fastening screw is used to fixedly connect the two parts of the terminal block. Watered down the fastening screw, and the contact can be separated easily. The reversing screw can reverse the polarity of the contact block. After tightening up the reversing screw, the polarity of the contact block can be changed. When loosening the reversing screw, the original polarity can be restored.

TB400-08 is widely used in electrical equipment with characteristics of high insulation voltage and insulation strength, excellent conductivity, and reliable connection. It is often seen in electronic control systems, switchboards, power distribution systems, and intelligent devices, etc. For example, its working principle can mostly be seen in valves, solenoids, relays, power switches, connectors, pilot lamps, motor starting systems, household appliances, power measurements, lighting fixtures, signal systems, etc. In these applications, TB400-08 can be used for power connections, carrying current, and adhering to cables.

TB400-08 permits the assembly of several hoop-shaped isolators between adjacent pair of terminal blocks. This isolator can separate the electrical circuits and thus reduce the risk of short-circuit accidents. And due to its compact size, it is widely used in the field of mechanical equipment, urban construction, maritime engineering, mining industry and so on.

TB400-08 can cope with harsh weather conditions, water resistance, and dust resistance. Its temperature resistance range is between -40 degrees Celsius to +105 degrees Celsius. The shell is made of flame-resistant plastic and equipped with a quick-connect terminal block and a thread with uniform diameter and pitch, which makes its installation and wiring easier. It is also provided with an integrated internal safety contact, integrated wire-locking device, and several different hole cutouts, further increasing its practicality and flexibility.

All in all, TB400-08 is a reliable connection product with excellent performance, mainly used in the application of low and medium current circuit connection. It can be applied in electric equipment with high insulation voltage, reliability, and good conductivity. With the advantages of water resistance, dust resistance, and quick-connect design, it has a wide range of application areas including valves, solenoids, relays, power switches, connectors, motor starting systems, power measurements, lighting fixtures, and so on.
