Terminal Blocks - Barrier Blocks

CB2142-0307 Terminal Blocks are a well-established form of barrier block terminal that has been used in electrical applications for over a century. They are typically used as a junction point between two components in a circuit, allowing for quick and easy disconnection or replacement of components.

Intended for use primarily on medium-voltage systems, these blocks are designed to reduce arcing between the conductors and the terminal itself, and eliminate the need for nuts and bolts. Also, due to their compact size, they can be adapted to many different applications and are especially ideal for use in tight spaces.

The CB2142-0307 Terminal Blocks feature a popular and recognized spring-clamp connection system, which provides safe and secure connections with visual indicators. This system is also self-adjusting and will maintain good contact throughout its service life. In many cases, these blocks can be subjected to shock and vibration, and provide a reliable alternative to nut and bolt connections.

The blocks are made of high-grade copper alloy and are conformally coated. The surface-treatment provides superior corrosion resistance and long service life. In addition, they are intended for use with cable sizes up to 16mm in diameter.

In terms of design, the CB2142-0307 Terminal Blocks feature an integrated window for visual inspection. This ensures that any change in the terminal block’s condition is clearly visible. Furthermore, the block can be securely mounted using either screws or locking elements.

Furthermore, CB2142-0307 Terminal Blocks are designed to be assembled and serviced using a variety of tools, including both conventional and magnetic types. In addition, the blocks feature a unique and removable tag printing plate that can be quickly replaced.

At the same time, the blocks are designed with an easy-to-release locking mechanism, and the terminals can be connected to wires without pre-assembly. As a result, these blocks can help to reduce installation time and cost.

In terms of the working principle, when a wire is placed in the spring-clip contact system of the block, the contact spring is pulled away from the insulation. As a result, an electrical current travels through the spring-clip and the contact is created. The current then flows along the cables connected to the block until it exits into the system.

In summary, the CB2142-0307 Terminal Blocks are a reliable and cost-effective solution for a wide range of electrical wiring. Utilizing a unique and advanced spring-clip technology and a self-adjusting design, this type of block ensures good contact and a long service life, while its unique window for visual inspection ensures changes in the condition of the block can be observed quickly and easily.
