Terminal Blocks - Barrier Blocks

The 3-140 terminal block is a type of barrier block that is widely used in various electrical and electronic applications. It is a small, compact, and lightweight unit that can be used for reliable power connection. The unit is well-suited for applications with high electrical loads, such as power conditioning and distribution. It has a unique design that separates the live electrical wires from the non-live ones, so as to ensure a safe operation and to limit the contact between the live electrical components and the environment.The 3-140 terminal block is made of the material Polyethylene, which is a thermoplastic resin material that is resistant to water, dust, and corrosion. It is also very durable and can withstand high temperatures and pressure. Furthermore, the unit can be easily installed and serviced, allowing for easier maintenance and more reliable operation.The working principle of the 3-140 terminal block is simple and straightforward. The unit is constructed of two sides, an input side and an output side. The input side is typically the larger side, and it can have multiple terminals where the wires are attached. The output side is the smaller side, and it consists of two terminals where the wires are connected, while the other two are used for the connection of the end device.The connection of the wires is done with either screws or nuts, depending on the type of wire used. When the wires are attached, they form a closed loop with each other and the end device. When electricity is passed through the terminals, it travels through the wires and ends up in the end device. The end device then uses the electricity to perform its function.In conclusion, the 3-140 terminal block is a versatile and reliable barrier block that is widely used in many applications. It is made of highly durable materials that are resistant to water, dust, and corrosion. Furthermore, it is easy to install and service, allowing for easier maintenance and more reliable operation. It has a simple but effective working principle that ensures safe operation and limits contact between live electrical components and the environment.
