4-140

Barrier Blocks (otherwise known as terminal blocks or strip terminals) are a type of electrical connector widely used in industrial, commercial, and residential settings. They are used to join two or more electrical lines or wires together to form a continuous path or circuit. Barrier Blocks can be used in a variety of applications such as connecting switchgear, wiring systems, and control panels.

Barrier Blocks provide support and insulation for the electrical connections while also preventing the pins and wires from contacting each other. This reduces the possibility of short circuits or other damage to the wiring system. Additionally, barrier blocks can help to reduce wiring errors by providing clearly labeled pins and wires to prevent confusion when connecting the electrical lines.

The 4-140 barrier block system is a modular system consisting of two different types of parts. The first is a base module which has keyed rows and columns of entry points for the wire/cable connections. The second type of part is the fuse holder block which slides into the base module and provides mechanical and electrical connection between the pins and wires in the system. The fuse holder also provides fuse protection to ensure the protection of the connected wires and components.

This type of barrier blocks can be used in a variety of different applications. It can be used for the connection of power cables, lighting cables, or other low-voltage systems. It’s also ideal for the connection of control devices such as relays, solenoids, sensors, and boosters. The modular design also makes it easy to configure different configurations for specific applications.

The working principle of the 4-140 barrier block is relatively simple. The base module consists of keyed rows and columns of entry points for the connections. The sliding fuse holder block, when placed into the module, chooses the specific entry points for the connection. The pins and wires then slide into the entry points and are held in place with a strong spring clip. Through this mechanism, the wires and devices connected to the barrier block will be protected from any potential damage.

In summary, barrier block systems like the 4-140 offer a convenient and reliable way to connect multiple devices and wiring. The versatility of the system allows it to be used in a variety of applications, and the components can be easily reconfigured to meet the specific needs of the application. The keyed entry points and spring-loaded connection ensures a strong electrical connection and safety features to protect the connected wires and devices.
