Terminal Blocks - Barrier Blocks

432303-12-0 is a barrier block manufactured by Phoenix Contact. It is one type of terminal blocks, which are electrical connections that attach signal and power components to a circuit board. Terminal blocks make it easier to repair or modify equipment in a wide range of applications.

Application Field

The 432303-12-0 is designed mainly for the signal and control technology industry, where its ease of installation and removal make it ideal for connecting and disconnecting multiple parts of a given system as needed. It is especially suited for applications that require frequent or quick mounting and/or the usage of different combinations of components. Through its double connection, it makes it very easy to connect two cables in parallel, or a horizontal and a vertical cable independently of each other. With its robust design and UL and CSA approval, it is also suitable for industrial use.

Working Principle

The 432303-12-0 is a barrier block with a built-in capability for making connections between different cables. It consists of two separate contact chambers, each of which can accommodate up to eight clamping bridges. The bridge chambers can be locked in place by pressing the levers at the side of the terminal block. This locks the bridges inside and creates a secure connection. The connections are then further secured with screws, which requires the use of a flat-head screwdriver.

The 432303-12-0 is also designed to provide an easy and efficient way to disconnect the cables once the connection is made. This is accomplished by using the release levers that are located near the screws. By pushing on these levers, the bridges are forced outward and the connection is released, allowing the cables to be disconnected with ease and without damage.

The terminal block also provides a highly reliable and secure connection, as the internal components are made of highly resistant materials that prevent corrosion and pollution. Additionally, the double contact prevents any wire from getting pinched, and the even pressure on both sides of the bridge helps to maintain an excellent electrical contact.

Conclusion

The 432303-12-0 from Phoenix Contact is a reliable terminal block for making electrical connections in the signal and control industry. Thanks to its robust construction and design, it is also suitable for industrial applications. It is easy to install and to disconnect the cables when needed, and the double contact prevents any wire from getting pinched. Overall, the 432303-12-0 is an excellent choice for those who require efficient and secure connections.
