0387506317 is a type of terminal block known as Barrier Blocks, which are used in a variety of applications and can offer safety or electrical protection.

A barrier terminal block is designed to control the flow of current and protect electrical components from damage due to over-current or over-voltage. It comprises an insulating plastic housing, a set of removable barriers, and metal electrical contacts that can carry up to seven wires, or strands of different sizes. The barriers limits the movement of current so as to prevent an overload current from passing through the block and overloading the electrical components connected to it. It is also commonly used to limit the current flow to a few components, such as relays or transistors.

Barrier blocks are often used in industrial settings, as they provide a safe way to interface with a variety of electrical current carrying wires. They are used to connect electrical circuits in safety circuits such as emergency shutdown systems, motor starters, or other machine safety systems. The use of barrier blocks also eliminates the need for complicated wiring such as the use of twisted pairs of wire or multiple single wires.

Barrier blocks are also found in consumer products such as home entertainment systems and automobiles. In these applications, it allows for the connection of wires or other components such as power switches or gauges. In the automotive industry, it is common to use barrier blocks to connect the headlight, taillight, and electric fan circuits.

The working principle of barrier blocks is simple. The metal contact pads are separated by an insulator that prevents the flow of current past the barrier, thereby limiting the amount of current that can pass through the block at any given time. As current passes through, the contact pads create a resistance, which reduces the amount of current that can be passed through and protects electrical components connected to the block from damage. When the contact pads become saturated with current, the insulator prevents further current from passing through.

Barrier blocks are extremely durable and weather-resistant, making them ideal for use in industrial, automotive, and consumer markets. While some blocks are designed for permanent installation, others can be easily removed for maintenance or replacement. The removable feature is especially helpful in critical applications, such as emergency shutdown systems.
