A terminal block is a type of electrical connection device used in electrical installations and electronic circuits to join two or more wires, that are or need to be insulated from each other. They are widely used in the industrial world where external plugs and connectors are deemed too unreliable, and also increasingly used as the power distribution point for the cables of consumer electronics, providing a convenient central point for powering all associated electrical circuits. Another application domain is the semi-conductor industry, where terminal blocks are employed as the principal method of connecting the many different components of a circuit board.

Barrier blocks are specifically designed for circuits with higher current and voltage requirements than those met by terminal blocks. They provide a secure connection point for wires that are subject to potentially damaging interference or leakage current, and are commonly found in automotive and heavy industrial wiring applications. They are suitable for use in systems with higher amperage, currents, or voltages than regular terminal blocks, or where tight connections and very secure connections are required.

The 0391002203 terminal block is a standard barrier block, designed to provide a secure, reliable connection point for insulated wires of varying sizes, thicknesses, and amperage ratings. It has a 4 mm2 connector area, which can accommodate up to four wires with diameters of 2.5 mm up to 16 mm. The part is made of flame retardant ABS polyamide and has a maximum operating temperature of 105°C. The outside dimensions of the block are 50X50X42mm.

The 0391002203 barrier block works by providing a securely held place for the wires to attach and then securely holds them together mechanically. It uses an array of screws or clamping strips to achieve this, which are then covered with an insulation barrier to ensure that the connection between the wires is not affected by vibration, electrical impulse, or other contact stresses. The locking mechanism also ensures that the connection remains secure even if the block is rotated or tilted. This makes it suitable for applications in hostile environments, like those found in harsh industrial outdoor locations.

The 0391002203 terminal block is suitable for use in a wide range of domestic, industrial, and commercial applications, and is especially suited to applications involving multiple high-current carrying circuits. Its relatively compact design and convenient mounting options make it an ideal choice for applications in tight spaces. In addition, it provides a secure, reliable connector migration path between old and new systems, as it is compatible with legacy barrier connector systems.

The 0391002203 terminal block is well suited to applications in which there is interference or leakage current, as it provides a secure and reliable connection point that can withstand these adverse conditions. In addition, the insulation barrier protects the connections from vibration and other stresses, making it suitable for environments where there is frequent movement or temperature change. The locking mechanism helps ensure that the connection remains secure even after rotations or tampering, making it a safe choice for applications in hostile environments.
