The Hager control wiring terminal KT07B is a 7-pole connection component from the universZ series, specifically designed for use in control wiring installations. It provides a secure and reliable connection for control wiring with a cross-section of 1.0 to 2.5 mm². The terminal is suitable for use in industrial and commercial electrical installations where a stable and durable electrical connection is required.

Applications

The KT07B is used in installations where control wiring with a cross-section up to 2.5 mm² must be connected. Typical applications include controls in machine building, manufacturing plants, or in building automation, where multiple signal lines are connected via a common terminal. The terminal is rated for a nominal voltage of 500 V and supports a nominal current of 20 A, making it suitable for medium to high loads in control applications.

Functions and Equipment in Detail

The control wiring terminal KT07B features a 7-pole arrangement, allowing it to connect up to seven individual wires simultaneously. The connection cross-section ranges from 1.0 to 2.5 mm², covering a wide variety of cable types. The terminal is designed for rigid wires, meaning it is not intended for flexible or shielded cables. The universZ series is characterised by a modular design, enabling easy integration into existing control panels.

Technology Explained Simply

The terminal is rated for a nominal voltage of 500 V and a nominal current of 20 A. These values define the maximum electrical load capacity of the terminal under normal operating conditions. The voltage of 500 V makes it suitable for use in industrial and commercial installations, where higher voltages are common. The current rating of 20 A is sufficient for most control wiring that does not serve as main conductors for high loads. The terminal complies with REACh-SVHC and RoHS regulations, ensuring the use of environmentally friendly materials and environmental compatibility.

Compatibility and Accessories

The KT07B is part of the universZ series from Hager and can be combined with other components of this series to create complete control panels. The terminal is intended for use in enclosures and distribution boxes, particularly in installations executed according to DIN VDE 0603/1 or DIN 43 870. The terminal is not intended for use in explosive atmospheres, as no specific protection categories such as Ex or ATEX are specified.

Mounting and Installation

Mounting is carried out in standard control panels or distribution boxes. The terminal is inserted into the designated mounting openings and secured using the existing fastening elements. The connection wires are inserted into the respective terminals and tightened using the appropriate tool (e.g. screwdriver). The terminal does not require any special tools for installation, although correct fastening of the wires is necessary to ensure a secure connection.

Advantages in Operation

The KT07B provides a reliable and durable connection for control wiring. The 7-pole design enables compact and clear wiring, simplifying maintenance and servicing of the installation. The use of environmentally friendly materials and compliance with RoHS and REACh-SVHC contribute to sustainability and environmental compatibility. The terminal is designed for use in industrial environments where high mechanical and electrical loads may occur.
