Terminal Blocks - Barrier BlocksTerminal blocks with barrier blocks are electrical components used to join two or more electrical wires or cables together for easy connectivity. They are used mainly in industrial automation applications where there is a large number of wires and cables that need to be connected.Barrier blocks are terminal blocks that come with a barrier that separates the incoming power wires from the outgoing power wires. This separation helps to protect against accidental electric shock or shorting of the power lines, as it ensures that any electrical current coming from an unshielded power source is blocked, and only properly regulated and properly shielded power can flow through the block.The typical 7-142 terminal block comes with two inputs, each of which can accommodate two power lines, and the barrier block can be mounted on the terminal block which then serves as an enclosure for the entire component. This helps to protect the power lines from dust, moisture and other environmental elements that could potentially cause a shorting out of the lines.The general working principle behind the terminal block and barrier block is relatively straightforward. The barrier block ensures that only the properly regulated and shielded power can flow through the block, while the terminal block allows you to easily and securely connect two or more wires. As the barrier block separates the two power lines, you can rest assured that any accidental electric shock or shorting of power lines is prevented.Barrier blocks are also used in applications where there is a large number of wires and cables that need to be connected. The barrier block provides a rigid enclosure for the wires and cables, and it also helps to protect them from dust, moisture and other environmental elements that could cause damage. Additionally, the barrier block is designed with an integrated safety switch that can be used to completely disconnect a particular line in the event of a short circuit.The 7-142 terminal block with barrier blocks is a versatile component that is used in a variety of applications. It is designed to be able to accommodate both high- and low-voltage applications, and it is a reliable and cost-effective way to keep multiple power lines safely connected. In addition, the integrated safety switch ensures that the power lines are safely disconnected in the event of a short.
