The UK 5 N passage terminal block from Phoenix Contact is a component of connection technology used in industrial installations for secure and durable connection of cables. With a rated voltage of 800 V and a rated current of 32 A, it is suitable for use in electrical installations with medium to high loads. The terminal block features two connections and allows the passage of cables with a cross-section of 0.2 mm² to 6 mm². The nominal cross-section specification of 4 mm² refers to the recommended standard cross-section for optimal conductivity and heat dissipation. Mounting is done on standard rails according to DIN EN 60715, specifically on NS 35/7.5, NS 35/15, and NS 32, enabling universal use in enclosures and distributions. The terminal block is grey in colour, which is typical for industrial components and ensures good visibility during installation.

Passage terminal block is the central function of this product, as it allows cables to pass through the terminal block without creating a break point. This is particularly advantageous in installations where continuous cable routing is required, for example in power distribution or control wiring. The screw connection technology ensures a mechanically stable and electrically reliable connection. The screw is tightened manually or with a screwdriver, securing the cable firmly in the connection. The rated voltage of 800 V and the rated current of 32 A define the maximum operating conditions under which the terminal block functions safely. These values are crucial for selecting the appropriate terminal block based on the electrical load and voltage of the installation.

The terminal block is designed for cables with a cross-section of 0.2 mm² to 6 mm², with the nominal cross-section of 4 mm² serving as the recommended standard value. This value represents a compromise between heat dissipation, electrical conductivity, and mechanical stability. The mounting method on NS rails (NS 35/7.5, NS 35/15, NS 32) enables easy and standardised installation in enclosures and distributions. The grey colour is typical for industrial components and supports visual orientation in the enclosure.

Compatibility and accessories include a variety of supplements that extend the functionality of the terminal block. These include warning signs such as WS 4-6 or WS 3-6, used for marking terminal block rows. Identification cards (SBS 6:UNBEDRUCKT) and markers (UCT-TM 6) allow for individual labelling. Bridges such as FBI 20-6 (20-pole) or FBI 100-6 (10-pole) as well as insert bridges (EB 10-6) serve to electrically connect multiple terminal blocks. Insulating spacers and bridge insulating spacers (e.g. IS-K 4, ISSBI 10-6) prevent unintended electrical connections. End caps (NS 35/7.5 CAP) and end holders (E/UK, CLIPFIX 35-5) protect the ends of terminal block rows and facilitate installation. Reducer plugs (RPS) and short-circuit plugs (KSS 6) serve specific applications such as connecting different cable cross-sections or shorting terminal blocks.

Mounting is done by clipping onto the appropriate NS rail and then tightening the screws. The terminal block is designed for use in enclosed enclosures, requiring no special tools or additional mounting aids. The use of accessories such as step lugs (STL 10N/5N, STL 35/5) enables the connection of terminal blocks with different cross-sections.

Operational advantages include the reliability of the screw connection, easy mounting, and universal usability on standard rails. The terminal block enables clear and structured cabling, facilitating maintenance and inspection. The use of accessories such as identification cards or warning signs improves clarity and safety during operation. The terminal block is designed for use in industrial installations where high mechanical and electrical load capacity is required. The specifications for rated voltage and rated current ensure that the terminal block operates safely under the specified conditions. Mounting on NS rails allows for quick integration into existing enclosure systems.
