• Terminal Blocks - Barrier Blocks
  • Overview of the 432303-19-0 application field and working principle

    Terminal blocks are a type of electrical connector used for installing wires and cables quickly and easily. The number one application for terminal blocks is to quickly join a number of cables and wires in larger electrical systems. Terminal blocks are the connectors of choice for most long-term, commercial, and industrial applications as they are the most reliable, robust, and cost-effective connection method available.

    Barrier blocks, also known as Pin Header-Type Barrier Blocks, are a type of terminal block that has a facility to connect wires in-line with one another. They allow for simple connection of small numbers of cables to a larger electrical system without the need for complicated wiring and soldering. Barrier blocks are usually fitted with specification-headed pins and are then inserted into a panel mount to form the final connection point for each wire.

    The 432303-19-0 is a 3-position barrier block made from UL94V-0 rated Polyamide base material. It has shrouded pins to prevent accidental short circuits and dual hole entry points to simplify the connection of two wires at the same time. The 432303-19-0 is a spring terminal type barrier block that has an insulation resistance of 5000MΩ, making it ideal for use in electrical systems with high levels of electromotive force.

    When connecting wires to the 432303-19-0, it is important to use the correct size pins that can slip comfortably into the dual hole entry points and provide a secure connection between the two wires. The pins should also be of a suitable material that is resistant to corrosion and temperature extremes, and they should have good electrical conductivity. After the pins have been inserted, typically the block will be secured with a strain relief clip, which provides an additional level of security to the connection.
