What is Feed Through Terminal Block?

A feed-through terminal block is a type of electrical connector used to connect and terminate wires in electrical circuits. It typically consists of a plastic or ceramic housing with metal terminals inside.

The key feature of a feed-through terminal block is that it allows wires to be connected to both sides of the block, thus enabling the signal or power to pass through without interruption. This is achieved through a continuous metal conductor that runs through the block, allowing electrical continuity between the terminals on both sides.

Feed-through terminal blocks are commonly used in industrial applications where multiple wires need to be connected, such as control panels, machinery, and electrical cabinets. They provide a convenient and efficient way to organize and terminate wires, making installation and maintenance easier.

These terminal blocks come in various sizes and configurations to accommodate different wire gauges, current ratings, and mounting options, making them versatile for a wide range of applications. Additionally, some feed-through terminal blocks may include features such as DIN rail mounting for easy installation in standardized electrical enclosures.
