Terminal blocks are a common and versatile type of connection device, which is used in a wide variety of electrical installations and products. The term originates from the early days of electronics, when stationary blocks of connectors permanently mounted on a wall or post were the most common type of interconnection. In the intervening decades, terminal blocks have undergone numerous technological changes and advancements to meet the increasing demands of the electronics industry.Barrier blocks are a type of terminal block that utilizes internal pole discrimination isolators to protect electrical circuits from dangerous short-circuiting. This type of terminal block is particularly popular in heavy industrial applications, such as those dealing with high-voltage equipment, where the potential for high-temperature short circuiting is especially great. Barrier blocks have two sets of terminal posts, with a glass fiber, porcelain, or plastic insulating material separating the two sets of posts. This insulating material is vital to safe operation, as it prevents the two sets of terminals from shorting out against each other, which could cause dangerous current shock or ignite a dangerous fire. For example, the 325148-16-0 terminal block is designed for high-performance electrical applications, providing fool-proof safety and superior power density for a multitude of applications. This particular model utilizes flame-retardant polyamide housing and pole discrimination technology which provide superior protection against reverse polarity and short circuit conditions. Not only does the UL94V-0 flammability rating ensure superior safety, but also provides a high level of electrical and mechanical endurance. The quick-connect design makes for easy installation, with a maximum working voltage of 300V and a current capacity of 16A making it an ideal choice for a variety of electrical projects. When it comes to working principles, barrier blocks work similarly to other types of terminal blocks. Power circuits are connected to the first set of terminals, and the blocked-off second set of terminals can be ignored. When the first set of terminals are connected to the power circuit, a signal is passed through the terminal, causing an isolator to open, making the second set of terminals a dead-end and preventing electrical shorts. Once the power is removed from the first set of terminals, the isolator closes and the second set of terminals are safe to be connected, without worry of short circuit. Terminal blocks can provide a multitude of different benefits to an electrical circuit, from surge protection to insulation to current regulation. In general, terminal blocks with integral barriers are the most cost effective and economical way to protect and organize electrical connection points. By utilizing pole discrimination technology, the 325148-16-0 terminal block provides superior protection against short circuit conditions, while its quick-connect design makes for easy installation, and a high level of electrical and mechanical endurance.
