Terminal blocks are an essential electrical wiring tool that widely applied in many commercial and industrial fields. They commonly used to connect wires in multiple configurations, create mechanical strain relief for the wires, and to secure terminals against accidental contact and looseness. Terminal blocks come in different configurations, namely DIN rail, PCB, pluggable and screw terminals. A207403R46 performs as a barrier block in such group of terminal blocks.

Definition and Symbology of Barrier Block

Barrier blocks can be defined as a type of terminal block that is used to electrically connect two or more circuits, while preventing the two circuits from interfering with each other. They contain multiple terminals connected in a column, and the connection barriers that separate the multiple sections. Therefore, the exiting wires cannot cross over to the section above it without physically moving the barrier itself from the way. In terms of its unit of symbol, a barrier block is commonly represented by two sections of terminals with a dash line in between, as the following drawing.

Features and Benefits of A207403R46

A207403R46 is a 16-barrier block manufacturer by Phoenix Contact. It adopts the design of 5.08mm pitch, so that the terminals can be connected up to 16 lines. The primary benefit of this terminal block product is that it provides physical separation for up to 16 lines connecting to the same power supply. This allows you to protect the line from resonance interference, as different current frequency line can be separated without affecting each other. Furthermore, it also facilitates structured wiring, markings and easier maintenance for your circuit layout. It only requires a cross-section of 1.5mm2, and the tightening torque is 2.2 Nm, making A207403R46 ideal for signal and communication connections.

In addition, another main advantage of this terminal block is that it supports PCB connection as well, due to its special design. The double-sided lugs on its plug-in bridges provide quick and easy power feed for PCB\'s connections. The entire range of A207403R46 is designed to have the plug-in bridge, which allows easy connection of PCB\'s with no corresponding mating male part. The steel plated contact bridges increases the robustness and strength of the connection, enhancing the contact points between the PCB\'s.

A207403R46 Application Fields

Since the A207403R46 barrier block offers multiple benefits as discussed, this terminal block can be widely used in various application fields, such as the control cabinets, and the power distribution component. Control cabinets typically used in many industrial plants, and its purpose is to house and protect the electrical equipment from dust, shock, water spray as well as many other environmental factors. By using A207403R46, it offers protection to the connected terminals from overvoltage, overcurrent and overcurrent, further increasing productivity of the system.

Apart from industrial plants, this terminal block can also be found in the power distribution component. With its plug-in bridge design, the power source can be connected into the barrier block from the below part, making the maintenance and replacement process easier. Moreover, the double-sided lugs also provide secure connection to the power source, preventing any possible short circuit happening.

A207403R46 Working Principles

The working principle of A207403R46 works just like most barrier block, by separating the circuits into various different sections within the same block. By doing that, the signals can safely and effectively transmit without affecting other circuits. The basic operations for its working principle would involve the insertion of wires of the corresponding section, technically tight the screws with the appropriate torque and finally secure them with a switching mechanism to prevent the wires to become loose overtime. With that method, even high peak voltage can be applied into the terminal blocks without having any potential electrical problems.

Furthermore, the connections made on A207403R46 also increase the accuracy rate of wire configurations, as the small notch on the wire lid provides a threshold between the positive and negative terminals. Also, the special design of plug-in bridges allows the easy connection of power cables as well as multiple electronic elements, making it easier for the engineers to make changes to the configurations in the future.

Conclusion

In conclusion, A207403R46 barrier block is an essential part of the terminal blocks family, widely applied in both industrial plants and power distribution components. Its main features and benefits are to provide physical separation of the connected terminals as well as the plug-in bridges design. Moreover, with electrically separated and pre-drilled connections, it improves the accuracy of the circuit layouts and reduces the maintenance costs of the electronics devices.
