The ADT 2.5 2C terminal block from Weidmüller is a component of the A series, specifically designed for use in industrial electrical installations. It serves as a disconnect device in electrical circuits, enabling safe and targeted interruption of the circuit during testing or measurement work. The terminal is intended for use in enclosures and distributions, where flexible and secure circuit disconnection is required. Its design allows for easy mounting in standard rail systems and is intended for use in industrial electrical engineering.

Applications

The ADT 2.5 2C is used in industrial electrical engineering applications, particularly in enclosures, distributions, and control systems. It is suitable for safely disconnecting individual circuits during maintenance, servicing, or diagnostic work, without having to shut down the entire system. The terminal is ideal for applications requiring targeted disconnection of conductors to ensure worker safety and maintain the integrity of the electrical installation.

Functions and Features in Detail

The terminal block enables disconnection of electrical circuits, with the electrical connection achieved via a movable contact tongue. The terminal is designed for a conductor cross-section of 2.5 mm² and provides two connection points (2C), allowing the connection of two conductors within a single terminal block. Its design allows mounting in standard rail systems, enabling modular expansion of control systems. The terminal is designed for industrial environments and offers a robust construction.

Technology Explained Simply

The ADT 2.5 2C operates on the principle of a terminal block with disconnect function. The electrical connection is established via a movable contact tongue, actuated by a lever or screw connection. When needed, the connection can be interrupted by operating the lever, thereby disconnecting the circuit. The terminal is designed for a maximum conductor cross-section of 2.5 mm², making it suitable for medium to high current loads. The construction ensures a secure and reliable connection, which remains stable even with frequent operation of the disconnect function.

Compatibility and Accessories

The ADT 2.5 2C terminal block is compatible with various marking and identification components, aiding in clearer identification of connections. These include, for example, terminal markers in various sizes and colors, such as the DEK 5/5 PLUS MC NE WS or WS 10/5 M MC NE WS. These markers allow for clear identification of connections, simplifying maintenance and servicing. Additionally, end plates such as the AEP 4C 2.5 are available, which visually complete the terminal block and protect it from mechanical damage. The terminal is designed for use in standard rail systems, ensuring compatibility with other components of the A series.

Mounting and Installation

The ADT 2.5 2C is mounted in standard rail systems installed in enclosures or distributions. The terminal is inserted into the rail and secured via a mechanical locking mechanism. Conductors are inserted into the connection openings and secured by operating the screw connection or lever. The disconnect function is activated by operating the lever, interrupting the electrical connection. Mounting does not require special tools, although the use of an appropriate screwdriver or pliers is recommended to ensure a secure connection.

Advantages in Operation

The ADT 2.5 2C provides a safe and reliable disconnect function in electrical circuits, required for testing and measurements. Its modular design enables flexible expansion of control systems, and compatibility with various marking and end components simplifies maintenance and identification of connections. The robust construction ensures long service life even under industrial conditions. The terminal is easy to install and does not require special tools, making installation and maintenance efficient.
