Terminal Blocks - Barrier Blocks are integral components of any automation system where electromagnetic loads create potential hazards. The 1776315-5 barrier block helps to prevent the uncontrolled flow of electrical energy inside an industrial environment by containing current in a confined area, providing a secure conduit between components and machines. This type of device enables machine operators to work safely within the confines of regulations and prevent the spread of dangerous electrical current.

Overview of 1776315-5

The 1776315-5 Terminal Block is a 3 pole barrier block comprised of 2 rows of contacts arranged in a parallel configuration. Each module features two distinct, large insulating blocks, one for each row of contacts. Each row has three barrier slots which provide 4 mm spacing between each pair of contacts, allowing them to be electrically isolated. The barrier blocks also offer a separate grounding point for each contact.

Application Field

1776315-5 barrier blocks are typically used in hazardous areas such as circuit boards, drive systems, and other situations where reliable electrical connections between components must be maintained. The device can be seen in a variety of applications, such as heavy-duty machinery, automotive electronics, medical equipment, and various safety systems. The terminal blocks are also designed to withstand extreme temperatures and environmental conditions such as moisture, high winds, and corrosion.

Working Principle

The 1776315-5 terminal blocks make use of an insulated barrier block to securely insulate and separate two sets of electrical contacts. The device features three screws to attach wires and four barrier slots to provide a space between each pair of electrical contacts. Each of the contacts is designed to handle a nominal current rating of up to 58 A. The contacts of the terminal blocks are designed with an insulating coating that prevents the risk of arcing and short circuit.

The device includes a grounding point which, if utilized by the user, serves as an additional safety measure by creating an electrical connection between two components on the same electrical line. This protective measure prevents the risk of electric current flow between components and serves to protect workers and equipment from dangerous electrical stimulation.

Conclusion

The 1776315-5 barrier block provides a safe conduit for electricity between components and machines, facilitating a safe working environment. It features two distinct, large insulating blocks that provide electrical insulation and adequate spacing between connected electrical components. Additionally, the grounding point serves an additional measure of protection against electrical current flow between components. This terminal block is designed for use in hazardous areas and is composed of durable materials to withstand harsh environmental conditions.
