Terminal Blocks - Barrier Blocks

YK3031203000G are barrier blocks that are used as a terminal to make electrical connections. Barrier blocks come in various styles, including single-level, dual-level, and multi-level blocks. Barrier blocks feature a barrier or divider in the center of the block to separate power and control circuits and prevent interference between them.

Application Field of YK3031203000G Barrier Blocks

YK3031203000G barrier blocks are ideal for use in industrial control panels, especially where you need to separate power from control circuits. It adds safety to hazardous wiring system due to it’s zero risk of accidental unpinning. The barriered sections provide complete electrical isolation between contact points. It also eliminates the risk of cross-talk and common-mode interference between high and low-side circuits. Barrier blocks are also used in LED lighting applications. LED lighting is powered by multiple power sources and a barrier blocks with different center points can be used to ensure safe connections between the power sources.

Working Principle of YK3031203000G Barrier Blocks

YK3031203000G barrier blocks use spring-clamp technology. The spring arms on both sides of the terminal are made of elastomer materials, which can grip the conductor firmly and ensure good contact. When a conductor is inserted into the terminal the spring arms contact the conductor and resiliently compress, providing a reliable contact force between the conductor and terminal. The terminals also feature an insulation barrier in the center of the block which separates the power and control circuits. This ensures no interference and prevents contact between high power and low power circuits. The insulation barrier helps protect workers against the dangers posed by high voltage contacts.

Conclusion

YK3031203000G barrier blocks is an electrical connection terminal mostly used in industrial control panels and LED lighting applications. It features a connection in each side of the block, with an insulated barrier in between to keep electrical circuits isolated from each other. The connection is made by a simple spring-clamp technology, allowing for conductors to be inserted with a reliable contact. The insulated barrier adds safety to hazardous wiring systems, making sure the power and control circuits remain separated and preventing any interference or contact between them.
