The 2794903 application field and working principle encompass several different types of products. These products are typically referred to as terminal blocks, which essentially allow circuits to be connected together for either a permanent or simpler and more temporary setup. The main types of terminal blocks that are included are din rail, channel and power/ground splice blocks.

Din Rail Terminal Blocks

As their name implies, Din Rail Terminal Blocks are designed to be mounted on standard DIN rail. The DIN rail system ensures that they are securely held in place and, as a result, offer a more robust setup than other products on the market. As well as availability in the compact design with all of the terminals integrated into a single housing, they can also be found in design with separate terminals, commonly referred to as "jumpers" or "legs".

Often Din Rail Terminal Blocks are designed to only accept wires of a certain size, meaning they have a specific degree of current carrying capacity. Therefore, one of the key advantages of this type of terminal block is that it eliminates the need to manually calculate the current carrying capacity.

Din Rail Terminal Blocks are the most widely used type of terminal block, particularly in industrial settings. Not only are they readily available in a large variety of shapes, sizes, and colours, they are relatively easy to install and maintain.

Channel Terminal Blocks

Channel Terminal Blocks are an alternative to Din Rail Terminal Blocks and are typically used in more \'domestic\' scenarios where there is less pressure on the connections; although they can also be found in certain industrial settings. For use in domestic scenarios, Channel Terminal Blocks are typically designed for single wires, whereas in industrial applications they can be used for multiple wires with higher current handling.

Channel Terminal Blocks can be mounted onto either DIN rails or onto metal plates (e.g. return rails) which form the base for the connection. This eliminates the need for additional mounting brackets and provides a more compact and aesthetically pleasing connection.

The big advantage of Channel Terminal Blocks is that they are relatively easy to install. This is due to the fact that they are typically produced in pre-made lengths of standard wire sizes, and therefore the user simply needs to connect the wires to the blocks without measuring or cutting.

In addition, because they are typically used in environments with low pressure, there is minimal need for additional insulation or strain relief, making them an ideal solution for many electrical connection needs.

Power/Ground Splice Blocks

Power/Ground Splice Blocks are the least common of the terminal blocks, and typically used when the amount of power needs to be split between two distinct circuits. They are designed to provide a \'bridge\' between two circuits and allow the user to evenly split the power without sacrificing safety.

Power/Ground Splice Blocks are typically installed between two blocks of the same type, and are designed to only accept wires of a certain size. This helps to ensure that the power is split evenly between the two circuits, as well as maintaining a predetermined level of current carrying capacity.

One of the biggest advantages of Power/Ground Splice Blocks is that they provide a \'bridging\' solution without the need of cutting or splicing the conductors. This can help to eliminate potential faults and reduce the time needed to connect the two circuits.

Conclusion

In conclusion, the 2794903 application field and working principle encompass various different types of terminal blocks, each of which have distinct characteristics and advantages. The most commonly used type of terminal block is the Din Rail Terminal Block, due to its robust nature and variety of sizes and colours available. Channel Terminal Blocks are also widely used for more \'domestic\' applications, and thanks to their pre-made lengths and simplified installation, they are a popular choice for many. Finally, Power/Ground Splice Blocks are the least widely used, but provide a \'bridging\' solution which is ideal for splitting power between two circuits.
