Terminal blocks are electrical connectors that make it easier to connect multiple circuits or separate them when necessary. Barrier blocks are one type of terminal blocks that consist of multiple copper terminals that terminate wire and provide a simple way to create a branch in a circuit, securely and safely. CB2142120 is a type of barrier block from Łucznik Company for use up to 400Vac/dc.

The CB2142120 is made up of a polyurethane body and a reinforced PBT base with a steel-plated top layer. It can provide higher strength and a higher electrical loading resistance than similar terminal blocks. Additionally, this barrier block can be used for quick trouble shooting of electrical problems to find the exact cause of the problem, since you can easily disconnect the troublesome circuit and still leave the block attached to the power line.

CB2142120 provides a cross mounting option that allows easier access to the terminals and provides an increased wiring flexibility. It is rated up to 20 A UL and 19 A CSA. You can insert a variety of single conductor wires of different gauges for different voltage applications.

The working principle of CB2142120 is straightforward. Electrical connections are made by inserting a single-conductor wire of the correct size or gauge into the terminal block and using insulated tools to tighten the block\'s screw and make the connection. The electrical connection is finished when the block\'s clamp pulls down and compresses the wire, successfully creating a solid connection.

In addition to its applications in residential, commercial and industrial fields, CB2142120 can be used in a variety of applications, such as in panel wiring, terminal wiring, lighting and control, audio and video systems, and power distribution systems. It has become one of the most reliable and efficient terminal blocks for these applications due to its insulation material and internal structure, which guarantee a secure and reliable electrical connection.

CB2142120 has become one of the most popular barrier blocks due to its superior electrical functionality and reliability. Its polyurethane body and reinforced PBT base make it strong and durable, while its top steel-plated layer ensures secure connection between the terminals and the wires. Furthermore, its cross mounting option makes it easier to access the terminals and its wide range of single-conductor gauges makes it applicable for various voltage applications up to 400Vac/dc. It is a reliable and efficient choice for the aforementioned applications, and it has become the go-to barrier block for electricians and IEC professionals.
