Terminal Blocks - Barrier Blocks

YK5020413000G is a type of terminal block commonly referred to as a barrier block or continental block. The block is a commercialized version of German electrical engineer Hugo Stotz’s pioneering work in the 1920s. Stotz recognized that a barrier block and a terminal block could be combined in one unit, thereby allowing users to jump between any number of terminals without the need to rewire.

Application Field

Barrier blocks have a wide range of applications, but are most commonly used in control cabinets and panels. Some of the most common uses include panel wiring, industrial control systems, wire-to-board power connections, test points, and distributing multi-core cables. Barrier blocks are also commonly used in medical laboratories, educational institutions, and other applications requiring multiple jumpers.

Functionality

The YK5020413000G barrier block features two mounting options: screws and feed-through top. The former provides zamp flexibility and is more secure than the latter. The block can also be fastened via the use of clips, which makes it simple and easy to secure the block in place. It features spring-loaded terminals with contacts (UK) made of polished brass, with a 5 mm width and 8mm spacing. To put it simply, the YK5020413000G block allows for secure and reliable connection and disconnection of multiple electrical circuits in an efficient and cost-effective manner.

Working Principle

Unlike traditional terminal blocks, the terminals on the barrier block are arranged in a grid, thus allowing for simultaneous connection and disconnection of multiple terminals. This makes the block ideal for use in demanding applications that require multiple electrically isolated connections. The terminals of the barrier block do not have to be wired in the same direction, making the block easy to connect and unplug. The terminals also feature a provided strain relief for enhanced durability and a low insertion force on the screw terminal, allowing for an easier installation. When connected to the rails, the terminals on the block distribute electricity across the desired connections. The electrical connection between terminals is provided through the barrier strip in the shape of a bridge. As electricity passes through these connections, it remains insulated from ground potential or other external voltages, thus preventing accidents and dangers.

Maintenance & Routine Inspection

Like all other types of electrical terminal blocks, barrier blocks should be routinely inspected for any signs of disconnection or broken components. If any such signs are present, it\'s important to have a technician solve the issue before reconnecting the block. Additionally, it\'s important to check and make sure all wiring is firmly attached and that the screw or pole terminals remain tightened. If any noticeable changes are detected, the blocks should be replaced immediately to avoid any safety risks.

Conclusion

To sum it all up, the YK5020413000G barrier block is an electrical terminal block used to connect and disconnect multiple electrical circuits in an efficient and cost-effective manner. It features spring-loaded terminals with contacts made of brass and it should be maintained regularly with inspects so that its components remain in good condition.
