What are Barrier Blocks ?
Barrier Blocks are specialized terminal blocks designed to provide electrical isolation between circuits while allowing for secure connections. They are commonly used in applications such as production electronics assembly and maintenance. Important specifications for selection include Current Rating (Amps), which ensures the block can handle the required load; Number of Circuits, which determines how many connections can be made; and Barrier Type, which affects the level of isolation provided. It is crucial for procurement teams to validate lifecycle status and consider alternate-source options to mitigate sourcing risks.
