Terminal Blocks, defined as a set of electrical connection terminals used to connect electrical wires, are a commonly utilized electrical component in power distribution, automation, telecommunication and measurement applications. Among the various types of Terminal Blocks, Barrier Blocks are an important subset that provide effective insulation, overvoltage and overload protection for the electrical components they serve. The 432612-02-0 Barrier Block is a particular type of insulated Barrier Block well suited for harsh industrial applications, such as automotive, traction, automotive OEM and renewable energy systems. The block features a superior level of resistance to shock, vibration and high temperatures; it is both UL and cUL approved, has multiple connection points, and offers a wide range of current and voltage ratings.The working principle behind 432612-02-0 Barrier Blocks is based on how it is designed and constructed. To provide effective insulation, the block is constructed with an insulating body composed of a high-impact, flame-retardant Polyamid 6.6 material that is further reinforced with metal clips between the two connection terminals. The top terminal is then exposed to the cables’ current flow and conducts the current to the bottom terminal, where it is then distributed to the other components. The metal clips are designed to firmly grip the wire, so as to ensure a secure connection and ensure minimal contact resistance. The block is also designed with an internally installed fuse link, which provides additional protection from short circuits, overloads and overvoltages.The application field of 432612-02-0 Barrier Blocks is vast, given its superior insulation and shock-resistant features, broad operating voltage and current range (400V AC/3A - 1000V AC/6A) and its UL/cUL approval status. It is most often applied in industrial power systems, including automatic control systems, rail power systems, traction power systems, drive control systems, motor control systems, lighting control systems, communication power systems, and distribution systems. The block is also found in renewable energy systems and can be used in both mobile and stationary industrial applications.In summary, the 432612-02-0 Barrier Block is a reliable and cost-effective component solution for harsh industrial applications. It is notable for its superior insulation, shock-resistant features, broad voltage and current ratings, and UL/cUL approval status. As a result, it is utilized in a large range of power, communication, measurement and automation systems.
