431213-25-0 Application Field and Working Principle

Connector blocks, also known as terminal blocks, are used for bridging electrical connections between two points. These common blocks, often adopted in the engineering, automotive and electronics sector, come in different versions and one such type of these blocks is the 431213-25-0 terminal blocks - also known as barrier blocks.

Barrier blocks are used to make electrical connections between two or more conductors in one position. It allows for different insertion needles and suitable for insertion of wide range of wires, stranded or solid. It can support multiple points and potentially even a terminal and ground connection in the same point.

Compared to standard terminal blocks, barrier blocks are composed of an insulation plate or barrier material which stretches between the two set of terminals. It measures the resistance and does not allow direct contacts between the two opposite sides.

The terminal blocks have their own chip card slot with two pieces and are Class FUL approved. This approval means it is specially designed for high copper content and high contact pressure. The terminal blocks also feature a purge screw and earth wire, making sure it meets all safety requirements needed.

The operating temperature range for these blocks is -25 to +80 degrees Celsius which makes the blocks suitable for most industrial applications. The 431213-25-0 terminal blocks come in different color variations and sizes making it a versatile and durable electrical connection solution.

The applications for these barrier blocks are widespread within the industry. They are common for electrical panels and control system circuits. The locking mechanism of the terminal blocks and their design makes them versatile for slicing in small and tight spaces, which makes them one of the most widespread connection solutions used by the automotive and engineering industry.

The working principle of the 431213-25-0 terminal blocks is fairly simple. When the two pieces are put together, by either hand or tool, contact is made through the center insulation barrier of the block. The contact is then completed with the connection of the metal screws which hold the two pieces together.

The contact is further improved by the specific clamping design of the blocks. The current is then conducted and distributed through one block, allowing for easy connection of the two different pieces. This makes the 431213-25-0 terminal blocks a versatile and reliable electrical connection solution and ensures safe operation.
