Barrier blocks, sometimes referred to as terminal blocks, are components used to make electrical connections between two or more wires. They are typically used to connect wires from separate components together as part of a complete circuit, and come in a variety of sizes and shapes depending on the complexity of the connection.

A 7-796985-4 is a type of barrier block and is one of the most common used in industrial applications. It has a total of 8 wire slots, allowing up to 8 pairs of wires to be connected at the same time. It has two primary pieces: 1) the base, which provides stability to the system and helps hold the connections in place, and 2) the barrier, which prevents accidental shorts or other contact with the wires.

In terms of application, the 7-796985-4 is widely used for controlling and protecting instruments connected to complex wiring systems, such as electrical motors, pumps, circuit breakers, and even lighting systems. It is also used in industrial applications to enable over-current protection on large-scale equipment, such as those found in factories and manufacturing plants.

The working principle of a 7-796985-4 barrier block is relatively simple. It is essentially an arrangement of terminals and contacts, where each contact is able to accommodate one pair of wires. The base of the block supports the connections, allowing them to be easily inserted and removed from the terminals, while the barrier prevents accidental short circuits or contact between wires.

Once the wires are inserted into the block, they are firmly held in place by a spring mechanism which protects them from any external forces. Additionally, the connections can be easily tested using a voltmeter, as the contacts provide a low-resistance path that can be measured with the voltmeter.

The 7-796985-4 has a number of advantages over standard terminal blocks. It is easy to install and replace, and can be used with a wide variety of wire sizes. Additionally, it can be mounted on either vertical or horizontal surfaces and requires no additional space for mounting. It is also capable of handling high-currents, making it ideal for large-scale applications.

Overall, the 7-796985-4 barrier block is a reliable and cost-effective solution for making electrical connections. It has an easy-to-use design which makes it perfect for industrial applications and can be used for a variety of purposes. The block is also highly reliable, with its sturdy spring mechanism providing a secure connection that is able to withstand high-current loads.
