The UK 16 BU passage terminal block from Phoenix Contact is a component for secure and reliable connection of cables in industrial electrical installations. It serves as a transfer terminal, where an electrical conductor is passed through the terminal, establishing a connection at both ends. The terminal is finished in blue and designed for use in enclosures and distribution units, where a stable and durable connection is required.

Applications
This terminal is intended for use in industrial electrical engineering, particularly in enclosures, distributors, and control systems. It is suitable for applications requiring connections of cables with a cross-section from 0.5 mm² to 16 mm². Installation is carried out on standard support rails in accordance with DIN EN 60715, particularly on NS 35/7.5, NS 35/15, and NS 32. These mounting types are widely used in the electrical industry and enable quick and secure installation in standard control panels.

Functions and Equipment in Detail
The terminal features two connections, implemented via a screw connection. This allows for a mechanically secure fastening of the cables, where the screw presses the cable firmly against a contact bridge. The maximum rated voltage is 800 V, making the terminal suitable for high-voltage applications in industrial environments. The rated current is 76 A, defining the electrical load capacity of the terminal and ensuring stability even under higher loads. The blue color serves as visual identification and is commonly used for terminals employed in power distribution.

Technology Explained Simply
The terminal is designed as a passage terminal, meaning the cable is drawn through the terminal and connected at both ends. This enables a compact and efficient connection, especially in tight control panels. The screw connection ensures a secure contact that remains stable even under vibrations and temperature fluctuations. The cross-section range of 0.5 mm² to 16 mm² makes the terminal universally applicable for various cable types, from fine control cables to heavier power cables.

Compatibility and Accessories
The terminal is compatible with various support rails, including NS 35/7.5, NS 35/15, and NS 32, which are standard in industrial electrical installations. As accessories, various test plug sockets (e.g. PSBJ 4/15/6 RD, YE, BU, BK) are available, enabling safe testing of connections. Additionally, partitioning plates (ATP-UK), markers (UCT-TM 10, UC-TM 10 CUS), separation washers (TS-K), insert bridges (EB 10-10, EB 3-10), toothed strips (ZB 10 unprinted, ZB10,LGS:L1-N,PE), warning signs (WS 4-10), and end caps (NS 35/7.5 CAP) can be used to optimize installation, improve clarity, and enhance safety. Support rails in various versions (e.g. NS 35/15 UNPERF, NS 35/7.5 AL UNPERF, NS 32 UNPERF) are also available to adapt installation to the respective control panel.

Installation and Mounting
Mounting is performed by simply inserting the terminal into the corresponding support rail. The terminal is slid into the rail and secured by the rail’s shape. Cables are fastened at both connection points using screws. Installation requires no additional tools other than a screwdriver or an appropriate wrench. The terminal is designed to be easily inserted into the rail, ensuring secure fastening.

Operational Advantages
The terminal provides a reliable and durable connection that remains stable even under industrial conditions involving vibrations, temperature fluctuations, and mechanical stress. The screw connection ensures a secure contact, avoiding additional connection issues. Compatibility with various support rails and the extensive accessory range enable flexible and adaptable installation. The clear color coding facilitates identification and maintenance during operation.
