Terminal Blocks - Barrier Blocks

The 431603-16-0 is a popular terminal block model offering barrier blocks for a large variety of applications. This model is part of a family of terminal blocks, which can be divided into two basic groups: terminal blocks with a snap-in locking device, and barrier blocks with a special contact chamber for wire connection. Both types can have a different number of terminals and are designed to meet different electrical requirements. The 431603-16-0 is a barrier block type with 16 terminals.

Application Field

Barrier blocks find use in a variety of environments. Examples include applications such as power distribution, control systems, machine interfaces, fabrication processes, and more. Barrier blocks are also used in hazardous areas and in areas with a high degree of dust or contamination.

The 431603-16-0 barrier block is designed for housing directionally oriented electronic components, with protection against voltage and shock. It can be used in combination with a wide range of contact systems, such as crimp, spring, or tine types, and can be used to broadcast voltages up to 250V (RMS) in AC circuit control.

The block can also be used to broadcast signals in low-voltage applications, including computer systems, equipment control systems, and telecommunication systems. In addition, it is used in power supplies, inverters, rectifiers, AC drives, and other components of electrical systems.

Working Principle:

The working principle of the 431603-16-0 barrier block is simple. It consists of a metal housing, with a contact chamber in the center. This contact chamber is closed at the top by a seal that connects all the contacts by a current-carrying hollow tube when the block is in the closed position.

The hollow tube is insulated on the outside by a plastic jacket, which is continuous around the outside of the block. Each of the contacts is connected to the tube with a spring connection, ensuring good electrical connection, and positive contact retention.

A mechanical interlocking mechanism, referred to as an actuator, is used to secure the block in the closed and locked position when in use. The actuator is also used to unlock the block, allowing it to be removed for cleaning or replacement.

The 431603-16-0 is designed with a large contact locking mechanism, which ensures that the terminal block is securely locked in place when opened and closed. This mechanism prevents accidental connection and disconnection of the contacts inside the block.

The block is designed to be resistant to corrosion, making it ideal for use in harsh environments. It can be used in applications with temperatures ranging from -60°C to +250°C (-76°F to +482°F). The housing is rated IP20, providing a degree of protection against access to live parts during normal operation.

The 431603-16-0 has a variety of features, including anti-looseness of contact screws, reliable electrical connections, and ease of operation. It is also CE and UL certified, ensuring reliability and safety of the block in any environment.

The 431603-16-0 is a high-quality, cost-effective terminal block, which offers superior performance in a variety of environments and applications. Its design ensures reliable electrical connections and ease of operation, making it a popular choice for many types of applications.
