Terminal blocks - barrier blocks, known by the product code 1546965-9, are a versatile electrical component used to connect electrical power to electronic circuits. Examples of applications include power supply, power circuit boards, and motor control. These blocks are designed to ensure a safe, reliable connection between two devices, without the risk of short-circuiting or shock hazards.

The primary function of a barrier block is to provide an isolated termination point for individual circuits. This enables multiple circuits to be connected without fear of cross-circuiting or shorting. In other words, it is a means of dividing an electrical circuit into several distinct sections in order to make repairs or modifications easier and safer. Barrier blocks are typically used in applications where primary power is delivered to one area of a system and then distributed to individual components or groups of components.

Barrier blocks are available in a variety of configurations, including standard, jumper, and relay blocks. Standard terminal blocks are designed to join two points of an electrical system, such as a power input and output. Jumper blocks are essentially a series of terminal blocks that are connected by a metal or plastic bridge. This allows for multiple connections between two points, allowing for multiple circuits to be connected to one master. Relay blocks are designed to provide a switchable point of connection between two points in an electrical system.

In general, barrier blocks are constructed from a sturdy polymer or metallic material that can withstand high temperatures. The contacts are usually made from copper or nickel-plated brass and feature an easy-to-slide wire clamp system. The barrier itself is usually made of a sealant material, such as epoxy or silicone, in order to protect against moisture and corrosion.

When it comes to the actual working principle of barrier blocks, it all depends on the specific design. Generally speaking, the basic design of a barrier block consists of an insulated base plate, terminal posts, and a barrier strip. Two wires are connected to each terminal post and the barrier strip is used to connect the two pairs of terminals. When power is applied to the terminals, an electrical connection is formed between the two wires, thus allowing current to flow. Typically, a barrier block is designed to handle up to a certain amperage load.

In summary, terminal blocks - barrier blocks, which are identified by the product code 1546965-9, are used to provide a reliable, insulated termination point between two separate points of an electrical system. They can be used to distribute power to individual circuits or provide a switchable point of connection between two points. Barrier blocks come in several different configurations and are constructed from durable materials that can withstand high temperatures and protect against corrosion. The working principle of a barrier block is dependent on the design, but generally the two wires connected to each terminal are connected by a barrier strip to form an electrical connection when power is applied.
