Terminal Blocks - Barrier Blocks

430101-25-0 is a Barrier Block from a wide portfolio of Terminal Blocks which are designed for speeding up wiring times and preventing accidental disconnections. These Terminal Blocks offer robust design, various connection technologies and a choice of European, British and American panel cut out form factors to meet customer needs.

Application Field

430101-25-0 is designed to provide a reliable connection between the different lines of the electronic circuit. This Barrier Block is ideal for a variety of application fields such as PLCs, HMI, DCS, industrial automation, automotive and office automation systems. Additionally the 430101-25-0 is also suitable for direct plug-in or as a part of machine hosting a large number of different electronics, connectors, switches, relays and other components.

Working Principle

The 430101-25-0 Barrier Block is a versatile connection device. It consists of a black plastic body and three rows of terminals. Two of the three rows are electrically isolated from each other by means of two sets of terminals on a higher level- the barrier. This allows the user to separate higher power carrying lines from the smaller signal lines which require higher electrical insulation, thus eliminating the risk of short circuit between them. The third set of terminals provides a connection for the common ground which identifies the block as a Barrier Block.

The 430101-25-0 provides pins with an increased contact area, thus creating a more reliable connection between the two lines. This is achieved via a double-wedge type pin to socket design. Additionally, the terminals are designed with a screwless connection technology for easy installation, a key lockable snap-in feature and a contact status indicator which inform the user when a successful connection has been established.

Conclusion

The 430101-25-0 provides an efficient and reliable connection between power carrying and signal lines which requires a high degree of electrical insulation. This Barrier Block is designed with a double-wedge pin to socket technology, screwless connection system and contact status indicator for maximum protection and ease of use. It is suitable for various application fields such as PLCs, HMI, DCS and industrial automation systems. Additionally, it has a choice of European, British and American panel cut out form factors to meet customer needs.
