0387007803 Application Field and Working Principle

0387007803 Terminal Blocks – Barrier Blocks are used extensively in industrial, medical, utility, HVAC, and commercial construction and field services applications that require continuity and protection for high-current control components. Barrier Blocks are available in various sizes and configurations, providing a large variety of connection opportunities.

The 0387007803 barrier blocks, also referred to as junction blocks, are popularly used for wiring motors on conveyors, running multiple lines of control from a single source, and operating motor starters, switches, and other components. These blocks provide easily accessible terminals that greatly reduce the amount of time spent wiring while still offering excellent reliability, allowing for greater efficiency in the field.

These blocks are available in various current carrying capacities ranging from 5 amperes to 100 amperes. They also feature a variety of insulation materials, mounting configurations, and extra safety elements such as fuse clips and dust covers. For applications that involve higher current carrying requirements, up to 200 amperes, heavier duty Barrier Block models are available.

0387007803 Terminal Blocks – Barrier Blocks Working Principle

Barrier Blocks use a multiple spring capture system to carry the current, even at high levels of vibration or surges. The current is conducted through the contact system using pressure contact principles. The base is designed with slots containing terminals, where the electrical wire is inserted into the terminal body and then relocked with the terminal’s multi-spring capture system.

These blocks are uniquely insulated and feature a cartridge system for additional safety. The insulation materials used for the blocks are UL approved thermoplastics, providing excellent insulation and UV resistance.

The Barrier Blocks also feature a heat sink design that dissipates the heat generated by the block. This design ensures that the block does not overheat and guarantees its performance and reliability. In addition, the blocks come pre-wired with suitable cable, making installation and wiring relatively easy. The connection options are easily expanded and adapted, allowing changes to be made quickly and effectively.

Conclusion

The 0387007803 Terminal Blocks – Barrier Blocks provide an efficient and economical solution to many wire management problems. The ability to change connection options quickly and effectively, the protection provided by the various insulation materials, and the exceptional reliability of these blocks make them the ideal choice for a wide variety of control applications.
