1726118

Terminal Blocks - Wire to Board refers to the wiring connection between the circuit board and the terminal block. 1726118 is a plug-in type terminal block. It is usually used to connect the power line and signal line of the electrical control system, and it is an important electrical component in industrial electronics. 1726118 terminal blocks have a wide range of applications in the protection and control of automatic systems, instrumentation, and other electrical systems.

Overview

The 1426118 terminal block is a three-phase plug-in type terminal block with flat fingers. It is specifically designed for three-phase applications, and its base material is PA66. The product contains mounting plates and connecting plates, which have the convenience and features of both snap-in and screw connection, with a wide working voltage range of 500V AC. It is an ideal product for electrical wiring in the automatic control system.

Details

The 1726118 connector consists of mounting plates and connecting plates. The mounting plates are punched to fix the terminal. The connecting plates are pressed into a concentric circle, and the connecting wire can be clamped between the connecting plates when it is used. The connecting plates can be adjusted axially to make them adapt to the length needed for the different terminals but to ensure the reliability and stability of the connection. On the side of the connecting plate, the words “UR” and “UL” are printed, which indicate the connection sequence of the three terminals. Usually, the UL terminal indicates the zero line, and the UR terminal indicates the fire line.

Application Fields

1726118 terminal blocks are widely used in power circuits, power distribution systems, and signal circuits to connect power signals and current-carrying wires. It is a necessary component in the development and production of a variety of electrical products, especially in industrial electronic systems. Its wide range of applications include fuse protection, overload protection of motor and solenoid valves, power distribution, earthing, protection, and motor reversing. In electrical systems, it plays an important role in short-circuit protection, overload protection, and overvoltage protection.

Working Principle

1726118 terminal blocks mainly rely on the pressing plate of the connection finger to complete the connection of the circuit signal. The connecting plate stores the spring energy due to the elastic loading, so that when the connecting wire is inserted, the pressing plate is closed. When the connection is completed, the connection is firm and stable. Long-term vibration and impact will not cause disconnection, and the connection is reliable. The insulation protection of the terminal blocks is also very good, so that it can meet the requirements of the rated surge voltage of the circuit.

Conclusion

Terminal blocks - Wire to Board is a very important component in the electrical system, 1726118 terminal block is one of them. It is a three-phase plug-in type terminal block, which is espescially designed for three-phase applications. It is constructed of two parts-mounting plate and connecting plate and reaches a working voltage up to 500V AC. Its range application includes fuse protection, overload protection of motor and solenoid valves, power distribution, earthing, protection, and motor reversing. Its working principle mainly relies on the pressing plate of the connection finger to complete the connection of the circuit signal.
