Terminal Blocks - Barrier Blocks

Terminal blocks are composed of terminal strips, barriers and end plates. 0387290102 barrier blocks are one type of terminal blocks, specifically used for applications where the terminals must be electrically isolated from each other. Barrier blocks provide this insulation between each terminal by placing a barrier of insulating material between each terminal. Typically 0387290102 barrier blocks have two mounting holes on the base near one end plate.
Barrier blocks come in a variety of types and sizes, and the 0387290102 style of barrier block has a very simple and versatile design. The 0387290102 barrier block features two rows of terminals, with two mounting holes, spaced 3/4" apart on the base. The two rows of terminals are connected through a barrier, which helps to ensure electrical insulation between them. The block also features an end plate, which helps keep the wires from coming into contact with anything else in the application.

0387290102 barrier blocks are most commonly used in applications requiring the electrical isolation of a circuit. For example, they are used to electrically isolate multiple outputs of a programmable logic controller (PLC), or to provide electrical isolation for components in a machine or process control system. They are also used in lighting systems to electrically isolate the individual lamps. In addition to providing electrical insulation, 0387290102 barrier blocks are also used to reduce ground loops and reduce electromagnetic interference (EMI). By using barrier blocks, the electrical potential between two or more circuits can be maintained, thereby minimizing or eliminating the effects of ground loops and EMI.

The working principle of 0387290102 barrier blocks is fairly simple. The two rows of terminals are connected through a barrier, which provides electrical insulation between them. This results in two circuits, which are completely
