Terminal Blocks - Barrier Blocks

A21941804 is a type of terminal block, designed to provide an insulated barrier between two electric circuits, allowing reliable and safe electrical connections. In essence, it works by linking an input wire to an output in an electrical circuit, while preventing any electrical discharge from the input to the output. The barrier block is often referred to as a circuit breaker or lamp holder block in many applications, and is a necessary component to ensure safe power connections.

The A21941804 barrier block offers several advantages over other solutions, including strong and low-cost structure, high insulation, high reliability and low voltage drop. It can be used in a wide range of applications, such as electric power distribution, electric discharge lighting, control cabinets, transmission systems, industrial automation, aerospace systems and telecommunications.

In most applications, the terminal block consists of two plastic moulded pieces. One piece has the connectors, while the other piece holds the connection cable. To ensure the block is secured in the correct place, the blocks features surface mount technology and is designed to be screwed to a separate mounting plate. The terminals, made of brass or copper, offer a reliable connection and are designed to be soldered in place. The terminals are also designed for high current capacity and to minimise resistance, providing high insulation between the input and output.

The terminals are sealed with a self-extinguishing sealing compound, preventing any electrical leakage. This ensures the barrier is fully insulated and that the current cannot reach the output terminals, allowing for safe connections. This makes the block suitable for use in industrial and commercial applications where safety and reliability is required.

The most common and popular type of A21941804 barrier blocks are those used in control panels. These blocks are designed to accept both simple and complex control panel wiring. The blocks feature secured connections for the inputs and outputs, allowing for safe and reliable connections which won\'t become loose. Another advantage of using a terminal block in a control panel is that the wiring will be well-organised, reducing the time required to install or repair the wiring.

A21941804 barrier blocks are also used in many medical applications. Their insulated design ensures that sensitive medical equipment, such as x-ray machines and MRI scanners, can be operated without the risk of interference or electrical leakage. These blocks are suitable for use with medical cables, which are highly resistant to electrical interference.

A21941804 barrier blocks are designed for reliability and safe connections in electrical circuits. Their reliable, insulated design makes them an ideal choice for many different applications, offering cost-effective and intelligent solutions to complex electrical problems.
