Terminal Blocks - Barrier BlocksBarrier blocks, also known as terminal strips, are industrial connectors commonly used to control electrical wiring connections in a variety of industrial, commercial and residential applications. They are a type of industrial modular wiring systems used to connect multiple wires that have two sets of posts to avoid contact with each other and provide further protection against electrical shock.Barrier blocks come in different styles, including round, D-type, flat and panel-mount. The two most common types of barrier blocks are the single-sided and double-sided. Single-sided blocks allow the user to connect wires which don\'t require more than one contact. Double-sided blocks are able to connect multiple pairs of wires that are needed to complete a circuit. This type of terminal strip is more expensive than the single-sided version, but it is also the most secure option.Barrier blocks have four primary components: the housing, the bridge, the terminal clamp, and the contact. The housing is a plastic or metal enclosure that houses the other components. The bridge is the main contact between the two sets of posts, and it connects the terminals to the contact. The terminal clamp is used to secure the wires in place and hold them securely against the contact. The contact is a conductive material that carries the electrical current to the terminals.Barrier blocks are rated for voltage and current based on their insulation, contact material and construction. The higher the insulation rating, the higher the voltage and current rating. The most common ratings for barrier blocks are 600 volts AC, 400 amps AC, 100 amps DC, and 24 volts DC.Barrier blocks are commonly used in a variety of applications, including industrial, medical, industrial process control, and industrial motor control systems. They are also used in the aerospace, communication, and transportation industries.Barrier blocks provide several benefits for both companies and consumers. By providing a close connection between disconnected wires, they can increase the reliability and performance of an electrical system. Additionally, the compact design of barrier blocks can save space, decrease wiring costs, reduce the risk of electrical failure, and improve the safety of equipment and personnel.Barrier blocks have applications in the automotive, consumer electronics, medical, and military industries. They are used in the automotive industry for wire harnesses, terminal locations, voltage monitoring, and power relay boards. In the consumer electronics industry, barrier blocks are found in audio equipment, computer systems, and digital televisions. In the medical industry, barrier blocks are used in medical machines and devices such as MRI and CAT scanners, ultrasound machines, and anaesthesiometers. In the military, barrier blocks are found in communication equipment, navigation systems, and weapons systems.Barrier blocks are ideal for creating temporary connections and testing circuits. They are relatively straightforward to install and require minimal technical skills. Interchangeable components such as the terminal clamp, contacts and bridges allow for easy replacements if a component fails.Barrier blocks are meant to be used in wet or dry environments, and they can handle temperatures between -76 and +302° Fahrenheit (-60 and +150° Celsius). The contact material must be based on the customer’s unique requirements, in order to be able to withstand the current and voltage rating.In conclusion, barrier blocks are industrial connectors commonly used in multiple fields for creating and testing circuits. Their primary components are the housing, bridge, terminal clamp, and contact, and they are typically rated for voltage and current based on their insulation, contact material and construction. Used to control electrical wiring connections in a variety of industrial, commercial and residential applications, barrier blocks provide many benefits such as increased reliability, improved safety, and space-saving.
