Terminal Blocks - Barrier Blocks
7-796985-0 is an industrial grade terminal block known as a barrier block. It is a type of specialized electrical connector designed to make connections between conductor wires in a conductive system. It still has the same idea of easy and quick connection to and through connections from individual conductors, but with different designs for better safety.

There are two distinct parts in a barrier block: the terminal block and the barrier strip. The terminal block consists of multiple interconnected conductors, each designed to attach to a wire, while providing space for the wire to pass through. This includes both solder and screw terminals that can be permanently or releasably connected to a circuit board. Either system has its own applications but for the purpose of this article, will focus on the screw terminals.

The barrier strip consists of an insulated spacing between the two conductors that allows a small current to pass across the connection while separating the high current. The intent is to protect personnel from coming into contact with electric charges, or from touching and coming into contact with the high current.

The most common application for barrier blocks is in hazardous and high-current loads, but it is most commonly used in industrial electrical systems, such as for machine control panels, switchgear, and motor control centers. This is due to its versatility and ability to carry high currents safely. In these applications, the barrier block connector isolates the power supply from the control signal, and the screw terminals provide a secure connection.

The connector comprises individual conductors, and each conductor is designed to hold a wire. The conductors are secured to the connector base, and multiple blocks can be linked together using a jumpers. The jumping pins used in the terminal block are designed for quick and easy connection to each other, enabling the user to easily connect multiple conductors together without requiring the use of a soldering iron. The connections also use a silicone coating, which helps to ensure a foolproof connection by preventing the conductor from loosening and creating a short circuit.

Barrier blocks are used in a variety of applications and are available in a wide range of sizes and connecting systems for different applications. Other applications include networking panels, custom electrical wiring, and signal conditioning. It is also gaining popularity in residential and commercial settings. The connector also provides a secure connection, allowing connection without soldering, and enabling complex networks.

7-796985-0 barrier blocks are an integral part of many electrical systems, due to the assurance of safety, high current capacity, and easy and secure connection. The two sections of the connector provide a safe connection by separating the high voltage from the low voltage, and the screw terminals provide a secure and reliable connection.
