Terminal Blocks - Barrier Blocks 0391002211 Application Field and Working Principle
Terminal blocks are component level electrical connectors used to connect electrical wires for the purpose of transmitting and manipulating electricity. 0391002211 is a series of terminal blocks known as Barrier Blocks. They are designed to separate two different circuits while allowing them to be connected in a way that electricity can pass between them. Barrier blocks are used in applications such as industrial controls, emergency lighting, motors, and power distribution.
Overview
Barrier blocks feature two or more levels of circuitry enclosed with an electrically insulated barrier. For two-level barrier blocks, one level is designed to protect the lower level from over-voltage or heat, while the other level allows for the connection of individual electrical wires. Therefore, the barrier blocks allow for the circuit breakers to be connected while maintaining isolation and safety. Typically, two-level barrier blocks feature a protective terminal down the middle of the block.
Barrier blocks with three or more levels are designed to separate more than two circuits, typically to support multiple voltage levels. Each level of the barrier block is configured differently, with a protective terminal or diode down the middle and additional terminal points on each side that are used to connect the desired voltage levels.
Material and Specifications
Barrier blocks are typically made of high-grade plastic or copper materials due to their ability to withstand the high temperatures and voltage that can occur during use. They are mostly constructed with a U-shaped body, a pin, and spring-loaded cable sleeve. The body is designed to be screwed into an electrical panel for a secure connection. The pin is connected to the internal wiring barrier and the spring-loaded sleeve inserts the wiring in the middle of the block.
The size of the barrier block, as well as the number and size of its pins, can vary according to the required application. For example, there are two-level blocks of 8 poles with spacing of 5 mm, and three-level blocks of 30 poles with spacing of 5 mm. Similarly, two-level blocks can have either single-pole or dual-pole pins, while three-level blocks have three types of pins that vary depending on the type of circuit being used. The voltage rating and current rating of the block must also be taken into account when choosing the right component.
Working Principle
The working principle of barrier blocks is relatively simple. Electrical current enters the block via the pins, runs through the insulation barrier, and is transmitted to the other side of the block. The barrier ensures that the two electrical circuits are isolated from each other and cannot cause a short circuit or interference. It also provides the necessary voltage drop and insulation to protect electrical components from accidental contact.
Most barrier blocks also include protective features that help ensure safety when handling the device. For example, many blocks include a “bridge” between two pins, which can be used to establish a connection between them and confirm the block is properly connected. In addition, the pins can be easily removed by simply snapping out the pin from the block.
Applications
Barrier blocks are commonly used in industrial control applications, such as power distribution systems, motor control systems, and emergency lighting systems. They are an ideal solution for areas where it is necessary to separate two or more circuits while connecting them with a reliable and safe connection. They are also easy to use and provide protection from voltage overload, short circuits, and other hazards.
Barrier blocks are also popular in adjustable speed drives, programmable logic controllers, and renewable energy applications. In addition, they are used in automotive and audio equipment, consumer electronics, and medical equipment. In all of these applications, the barrier block can be used to ensure safe and reliable operation.
Conclusion
Barrier blocks are a versatile type of terminal blocks that can be used to separate and connect two different circuits. The 0391002211 barrier block series can provide reliable and safe electrical connections in a wide variety of applications, such as industrial controls, emergency lighting, motor control, power distribution, and more. They are constructed with high-quality materials and feature protective features that help ensure safety and prevent short circuits. Thus, they are a great solution for any application where safe and reliable electrical connections are required.
