The UK 16 through-conductor terminal from Phoenix Contact is a component of connection technology designed for secure and reliable electrical connection of cables in industrial applications. With a rated voltage of 800 V and a rated current of 76 A, the device is suitable for installations with high electrical loads. The terminal features two connections and enables the connection of cables with a cross-section of 0.5 mm² to 16 mm². Mounting is done on standard support rails of types NS 35/7.5, NS 35/15, and NS 32, ensuring universal installation capability in enclosures and distributions. The component is grey in colour, which is typical for industrial components and allows good visibility during installation.

Applications

The UK 16 is used in industrial electrical engineering, particularly in enclosures, distribution boxes, and control systems, where stable and durable cable connections are required. It is suitable for applications in manufacturing automation, power distribution, and machine building, where high mechanical and electrical loads occur. The terminal can be used in environments with increased reliability requirements, as it is designed for a rated voltage of 800 V, making it suitable for many industrial supply voltages.

Functions and Equipment in Detail

The terminal features a screw connection that ensures a secure and mechanically stable connection of the cables. Connection is made via screw connection, where the cable is inserted into the connection area and tightened using a screw. The permissible cross-sections of 0.5 mm² to 16 mm² cover a wide range of applications, from fine control cables to heavier power cables. The number of connections is two, allowing cables to pass through the terminal without creating an electrical contact between the cables.

Technology Explained Simply

The UK 16 through-conductor terminal is a passive component that does not perform any electrical function such as switching or control, but exclusively ensures the mechanical and electrical connection of cables. The rated voltage of 800 V means the terminal is designed for operating voltages up to this value without risk of insulation breakdown or overheating. The rated current of 76 A describes the maximum current load the terminal can withstand continuously without overheating or mechanical damage. Mounting on support rails of standards NS 35/7.5, NS 35/15, and NS 32 is done by clamping or screw fastening, depending on the rail type, where the terminal is inserted into the rail and fixed.

Compatibility and Accessories

The UK 16 is compatible with various support rails, including the perforated and non-perforated variants of types NS 35/7.5, NS 35/15, and NS 32. As accessories, various end holders such as the E/NS 35 N or CLIPFIX 35-5 are available, enabling secure fastening of the rail in the enclosure. Warning signs such as WS 5-10 or test plug sockets such as PSBJ 4/15/6 in various colours can be used additionally to support installation. Additionally, fixed bridges such as FBI 10-10 or FBI 2-10 are available to electrically connect multiple terminals. An end cap D-UK 16 can be used to cover the ends of the rail.

Mounting and Installation

Mounting of the UK 16 is done by inserting it into the appropriate support rail, where the terminal is slid into the rail and fixed using the rail fastening systems. The cables are inserted into the connection openings and tightened using the screw connection. Mounting does not require special tools, although a screwdriver or pliers are required to tighten the screws. Correct cable fastening is crucial for the electrical and mechanical stability of the connection.

Advantages in Operation

The UK 16 offers high mechanical stability and electrical reliability, making it suitable for use in demanding industrial environments. The use of standard support rails enables easy integration into existing enclosures. Clear labelling and standardised colour coding facilitate maintenance and replacement. The terminal is designed for long service life and requires no maintenance during normal operation, provided mounting instructions are followed.
