1501-YWY

Terminal Blocks - Barrier Blocks

1501-YWY is a type of terminal block, also known as barrier blocks, designed for applications where high levels of versatility are needed. For electrical assembly and wiring work they provide a convenient way of connecting high current wire connections and terminals together.

Application Field

Primarily used as an insulation block in electrical control applications, 1501-YWY blocks are typically used to provide a fixed separation between two electrical devices or circuits. This allows electrical power to be switched between these two areas without actually allowing the circuits to come into contact with each other.

Barrier blocks can also be used for grounding purposes. The connection between a ground and the negative terminal of the power source is made with the barrier block. This is commonly used in situations where the components of the system are made of different conductive materials.

Working Principle

Barrier blocks are designed to achieve electrical insulation between two points. The basic assembly consists of two blocks, an end block and a middle block, which are connected to each other by two aluminium strips running along the width of the blocks. This aluminium strip lets electricity travel through the length of the barrier block and connects all the internal components.

The end blocks and middle blocks are held together by two plastic pins pushing down on the aluminium strip. The pins are attached to the end blocks and when the centre blocks are inserted into the end blocks, the pins make contact with the aluminium strip, creating an electrical path. The two plastic pins also provide physical insulation thereby protecting the aluminium strip and the internal components from external electrical interference.

This setup ensures that there is no electrical contact between the end blocks and the middle blocks, thus providing the desired electrical separation. Additionally, the contacts made with the internal components can be changed and adapted as needed, making the 1501-YWY a highly versatile terminal block.

Conclusion

In conclusion, barrier blocks are essential for applications where high levels of versatility and electrical isolation are required. 1501-YWY blocks are designed to provide both electrical insulation and flexibility, allowing users to make a wide range of connections in their systems. Moreover, 1501-YWY blocks are easy to assemble and maintain, making them ideal for applications where high levels of complexity and reliability are needed.
