Terminal Blocks - Barrier Blocks

Barrier blocks are an integral component of many modern electronics enclosures. While they serve a common purpose, the individual models and technologies that make up barrier blocks are often very different. The 39400-0403 barrier block is a good example of a versatile and reliable terminal block.

Application Field

The 39400-0403 can be found in many applications, most notably in consumer electronics and home automation systems. It is well-suited for automotive and industrial applications due to its ability to handle high current and voltage. Additionally, its modular design makes it suitable for use in applications such as lighting control, HVAC systems and communication networks.

Working Principle

This barrier block is made of two parts: a top housing and a lower base. Each part features electrical contacts that match each other perfectly to ensure a reliable connection. The top housing contains two IEC/ISO standard connectors which allow for quick and easy connection of cables. The base contains a terminal block, which serves as the connection point between the top housing and the wiring. This terminal block is fixed in place by two screws, which secure the two parts together. Additionally, the terminal block contains an isolation barrier to help protect against electrical shorts.

In addition to the two IEC/ISO standard connectors, the 39400-0403 has a number of other features which make it an ideal choice for many applications. This terminal block is able to handle up to 8A current and 250V voltage. In addition, it features a 45 degree angle design, allowing for easier access and connection. Furthermore, it is rated IP20, meaning it is protected against touch by fingers and other objects larger than 12.5mm. Its construction is also shielded against interference from radio frequency or electromagnetic radiation. Finally, the terminal block is RoHS-compliant, meaning it is safe for use in any environment.

Conclusion

The 39400-0403 barrier block is a versatile and reliable terminal block that can be used in many applications. Its modular design makes it suitable for consumer electronics, home automation systems, lighting control, HVAC systems and communication networks. In addition, it is capable of handling up to 8A current and 250V voltage and is rated IP20. Additionally, the unit is RoHS-compliant and shielded against interference from radio frequency and electromagnetic radiation, making it a safe and effective choice for use in any environment.
