The UK 5 terminal block from Phoenix Contact, manufacturer's number 3004016, is an industrial connection terminal for use in control systems and automation technology. It is designed for secure and durable connection of cables in electrical installation technology. The terminal is intended for use in enclosures and control systems, where reliable current transmission between multiple cables is required. With a rated voltage of 800 V and a rated current of 32 A, it is suitable for medium to high loads. The terminal features two connections operated via a screw connection, ensuring a mechanically stable and electrically conductive connection.

Applications

The UK 5 terminal block is used in industrial electrical engineering, particularly in enclosures, control systems, drive technology, and automation systems. It is designed for use in installations with an operating voltage up to 800 V and enables connection of cables with a cross-section of 0.2 mm² to 4 mm². The terminal is intended for indoor use, with mounting on standard support rails. The mounting types include NS 35/7.5, NS 35/15, and NS 32, which are widely used in industrial electrical installations.

Functions and Equipment in Detail

The terminal features a screw connection that ensures a mechanically secure connection. The screw is manually tightened, securing the cable and establishing an electrically conductive contact. The number of connections is two, enabling the terminal to function as a passage terminal – current flows from one connection to the other. The terminal is grey in colour, which is typical for industrial connection technology. It is designed for cable cross-sections from 0.2 mm² to 4 mm², making it suitable for a wide range of applications in electrical installations.

Technology Explained Simply

The rated voltage of 800 V means the terminal is designed for electrical systems operating up to this voltage. The rated current capacity of 32 A indicates the maximum current the terminal can transmit continuously without overheating or damage. The screw connection allows for simple and secure cable installation, with the screw pressing the cable firmly against the contact. The terminal is designed for mounting on support rails according to NS 35/7.5, NS 35/15, and NS 32, which are standard in industrial electrical installations.

Compatibility and Accessories

The UK 5 terminal is compatible with various support rails, including NS 35/7.5, NS 35/15, and NS 32, in both perforated and non-perforated versions. Suitable accessories include fixed bridges such as FBI 2-6, warning signs such as WS 5-6, insulating sleeves in various colours (red, green, white), labelling cards, and individual covers. These components can be used to improve the organisation and labelling of the control system. The terminal can also be combined with switching bridges such as USBRJ 2-7 or test plugs such as PSBJ 3/13/4 to extend the functionality of the control system.

Mounting and Installation

Mounting is done on standard support rails according to NS 35/7.5, NS 35/15, or NS 32. The terminal is clamped onto the rail using a screwdriver or pliers. Cables are inserted into the connection openings and secured by tightening the screw. Mounting requires no additional tools other than a screwdriver. The terminal is designed for use in enclosures and control systems, with installation typically performed by skilled personnel.

Operational Advantages

The UK 5 passage terminal provides a reliable and durable connection for cables. The screw connection ensures a mechanically stable and electrically conductive connection that remains secure even under vibration or temperature fluctuations. The terminal is suitable for a wide range of cable cross-sections, increasing flexibility in use. Compatibility with various support rails and accessories allows flexible integration into existing control systems. The grey colour is neutral and matches the standard colour scheme of industrial control systems.

The terminal is designed for indoor use. Mounting is on support rails commonly used in industrial electrical installations. The terminal is not intended for outdoor use, as no specific protection rating (e.g. IP) is specified.
