The fuse terminal block UK 5-HESILED 24 from Phoenix Contact is a single-pole terminal block for mounting on standard support rails in industrial applications. It is designed for the secure mounting and connection of cables with an integrated fuse insert, where the fuse can be installed in the format 5 x 20, 5 x 25 or 5 x 30 mm. The terminal block is designed for use with glass or ceramic fuses classified in protection class G. The rated voltage is 24 V, and the rated current is 6.3 A, making it suitable for applications in control and automation technology with low current requirements.

Fuse terminal block is the product type, specifically designed for use in electrical circuits with integrated fuse functionality. The protection class G refers to the fuse type designation, intended for use in electrical installations with low to medium stress. The fuse types 5 x 20, 5 x 25, 5 x 30 define the physical dimensions of the fuses that can be inserted into the terminal block. The terminal block is designed for a rated voltage of 24 V, which is typical for control and automation systems in industry. The rated current of 6.3 A defines the maximum current load the terminal block can safely transmit.

Application areas include installation in enclosures, control systems, drive technology and other industrial electrical installations where a secure and easily accessible fuse function is required. The terminal block is designed for mounting on support rails of types NS 35/7,5, NS 35/15 and NS 32, enabling universal use in standard control panels. The connection type screw connection ensures a mechanically stable and electrically reliable connection of the cables. The rated cross-section of 1 mm² defines the recommended conductor cross-section for optimal performance, while the permissible cross-section range of 0.2 mm² to 4 mm² allows flexible adaptation to various cable cross-sections.

Functions and equipment in detail include the integrated fuse function, providing protection against overload and short circuit. The terminal block is finished in black colour, enabling visual coordination with other components in enclosures. Mounting is done by directly clipping onto the support rail, where the terminal block is fixed by the rail profile. The terminal block is not designed for use in explosive environments, as no corresponding approvals are mentioned.

Technology explained simply means that the terminal block creates a mechanical connection between cables, with electrical conductivity ensured by the screw connection. The integrated fuse protects the downstream circuit from excessive current load. The fuse is inserted into the terminal block and can be replaced as needed without having to switch off the entire circuit. The terminal block is not specified for use in damp or wet environments, as no IP protection rating is mentioned.

Compatibility and accessories include use with support rails of types NS 35/7,5, NS 35/15 and NS 32, which are standard in industry. Suitable accessories include support rails in various versions (perforated, non-perforated, galvanized, aluminium or copper), end holders, end caps, insert bridges, as well as tools such as screwdrivers. The combination with insert bridges enables connection of multiple poles, allowing the terminal block to be used in more complex circuits. The use of end holders and end caps ensures proper termination of the rail.

Mounting and installation is done by clipping the terminal block onto the support rail, where it is fixed by the rail profile. Cables are connected via the screw connection, with the recommended cross-section being 1 mm². The fuse is inserted into the designated holder. The terminal block is not specified for use in moving or vibrating environments, as no corresponding information is provided.

Operational advantages include quick and secure mounting, easy maintenance through fuse replacement, and universal usability on standard support rails. The terminal block enables clear circuit structuring, as the fuse is directly integrated at the connection point. The use of insert bridges extends functionality by allowing multiple poles to be connected. The terminal block is designed for use in industrial environments where high reliability and longevity are required.
