The Hager KH23C is a 3-pole main circuit branch terminal in universalZ design, developed for professional use in electrical installation systems. It enables safe and efficient distribution of main circuits in distribution boxes and allows branching of multiple conductors from a single main circuit. The terminal is finger-safe designed, ensuring enhanced safety during installation and maintenance. With a rated current of 80 A and a rated voltage of 400 V, it is suitable for typical industrial and commercial applications. The branch terminal is designed for conductor cross-sections from 2x25 mm² to 2x16 mm², allowing connection of both solid and fine-stranded as well as multi-stranded conductors.
Applications
The KH23C is suitable for use in distribution boxes where reliable and long-lasting distribution of electrical conductors is required. It is frequently used in building electrical engineering, for installation of power supply systems, and in industrial plants. The robust construction and finger-safe design make it particularly suitable for applications where access to connection points is necessary during installation or maintenance. The terminal is designed for use in enclosed switchgear, with dimensions (height 65.9 mm, width 69.2 mm, depth 45.5 mm) enabling compact placement in standard distribution boxes.
Functions and Equipment in Detail
The terminal features 6 inputs and 6 outputs, enabling flexible distribution of conductors. The connection type is screw-based, with a nominal torque of 2.80 Nm ensuring a secure and durable connection. Shock protection is ensured by the constructive design, minimizing the risk of accidents due to unintended contact with conductive parts. The terminal is halogen-free and RoHS-compliant, ensuring environmental compatibility and compliance with European directives for electronic devices.
Technology Explained Simply
The KH23C operates on the principle of a screw terminal, where conductors are securely clamped by a screw to ensure a reliable electrical contact. The 3-pole design enables distribution of three conductors (e.g. L1, L2, L3) from a main circuit. The finger-safe construction protects the user from direct contact with conductive parts, even if the terminal is not fully closed. The connection cross-sections of 1.5 to 25 mm² for solid conductors and compatibility with fine- and multi-stranded conductors expand the range of applications. The terminal is designed for screw mounting, enabling secure fixation in the distribution box.
Compatibility and Accessories
To extend functionality, the KH23C is compatible with the KH24C main circuit branch terminal 4-pole finger-safe. This can be used in similar application scenarios, especially when 4-pole distribution is required. The combination of both models enables flexible and modular design of distribution systems, taking into account the respective pole numbers and connection options.
Installation and Mounting
Mounting is done by screw fixation in the distribution box. The specified torque requirement of 2.80 Nm must be observed to ensure a reliable connection. The terminal is intended for use in enclosed switchgear, with dimensions enabling integration into standard distribution boxes. The finger-safe design facilitates installation, as connections are safely accessible without additional protective housing.
Operational Advantages
The KH23C offers long service life and high reliability due to its robust construction. The finger-safe design increases safety during installation and maintenance. Compatibility with various conductor types (solid, fine- and multi-stranded) and the clear structure with 6 inputs and 6 outputs simplify planning and execution of distribution systems. The RoHS compliance and halogen-free materials support sustainable and environmentally compatible installations.
