Terminal Blocks - Barrier Blocks are a type of device used to provide a physical and electrical link between two or more circuits. The 433100-21-0, specifically, is a terminal barrier for use in electrical control panels. It provides an easy, reliable and efficient way to connect and disconnect power and signal lines.

The 433100-21-0 is a two-part design consisting of an upper and lower part. The upper part contains a base with an insulator and contact pins which protrude through it. The lower part contains a plastic barrier between two contact plates, which allows electricity to flow between them only when closed. This configuration prevents contamination and short circuits by preventing contact between adjacent terminals or lines, and provides quick and easy access to disconnect and reconnect power or signal signals.

The 433100-21-0 is designed to be used in electrical control rooms, switchgear, motor control centers, and assembly lines. It can be used in combination with other devices, such as switches, contactors, and circuit breakers. Its general use includes power distribution, control wiring, sensor wiring, and signal wiring.

The 433100-21-0 consists of two distinct components – the contact pins and the plastic barrier. The contact pins provide an electrical path between the source and the load and are made of brass or copper plated with silver or gold. They are designed to withstand high temperatures, contact corrosion, and thermal cycling in order to ensure reliable operation. The plastic barrier is the intermediary component that prevents short circuits from occurring by allowing electricity to flow between adjacent terminals or signal lines only when closed. Both parts of the terminal block are constructed of Plexiglas which makes them durable enough to withstand wear and tear, providing a long service life of up to 20 years.

In applications where there is a risk of overloading, voltage spikes, or abrupt current flow, the 433100-21-0 offers adequate safety protection. The barrier between contact plates limits any current passing to a safe level, providing necessary protection. This terminal block also has an environmental protection rating of IP67, ensuring protection from moisture, dust, UV light, and extreme temperatures.

Installing the 433100-21-0 is easy and requires minimal tools, time and effort. The contact pins can be inserted directly into a support plate, or connected in a daisy chain. Depending on the application, the unit can be hard wired or connected with a plug-in connector. Inserting the contact pins into the support plate requires some force, but they are designed to snap into place quickly and securely, without the need for screws or other tools. The two contact plates can then be connected to the necessary accessories or electrical circuits using the appropriate cable or connection.

The 433100-21-0 is a reliable, efficient and safe solution for connecting and disconnecting power and signal lines. It provides easy access to disconnect and reconnect power or signal lines with minimal time and effort. Its high-temperature and corrosion resistance, environment protection rating, and sturdy construction make it suitable for use in a variety of applications. It is also an economical choice, requiring minimal maintenance over its long service life.
