The Spelsberg Mini 25-L is a junction box for use in indoor installations, particularly for standard applications such as lighting systems or connections in electrical wiring networks. The device is designed as an empty connection box without integrated terminals, serving as a base for mounting switches, sockets or other electrical components. The box is finished in grey and made from halogen-free thermoplastic, enabling safe and environmentally compatible processing. Dimensions are 89 mm (width) × 43 mm (height) × 38 mm (depth), making it suitable for compact installations.

Applications
The Mini 25-L is designed for standard indoor installations and can also be used in outdoor areas, provided the protection rating IP55 is sufficient. The IP55 rating ensures dust and splash water protection, safeguarding the box against mechanical impacts and water entering from any direction in the form of splashing. This makes it suitable for areas with increased humidity, such as kitchens, bathrooms or covered outdoor installations. The box is not intended for direct exposure to heavy rain or submersion in water.

Functions and Equipment in Detail
The box features self-sealing entry membranes that enable watertight and dustproof cable gland connections. These membranes are integrated into two rear and ten side openings, ensuring flexible cable routing. The sealing range is 8.2 to 12.5 mm, allowing adaptation to various cable diameters. The external mounting points facilitate installation on walls or other surfaces without requiring additional fastening elements.

Technology Explained Simply
The protection rating IP55 means the box is protected against dust and splashing water. This is particularly important in areas where moisture or dirt could affect the electrical installation. The rated voltage Ui=400 V AC defines the maximum voltage the box can safely handle, which is sufficient for typical electrical installations in buildings. The box is certified to DIN EN 60670-1/-22 (VDE 0606-1/-22), confirming compliance with European standards for electrical installation boxes. The use of halogen-free thermoplastic reduces the formation of toxic smoke gases in case of fire, increasing safety.

Compatibility and Accessories
The Mini 25-L is designed for cables with a nominal cross-section of 2.5 mm², which is sufficient for many standard installations in residential and commercial buildings. The box can be combined with various electrical components, such as switches, sockets or other connection elements, which are installed into the box. The self-sealing membranes enable secure and tight cable routing, ensuring the integrity of the installation.

Mounting and Installation
Mounting is done via the external mounting points, which allow secure fastening to walls or other surfaces. The box is inserted into the designated opening and fixed with screws or other fastening means. Cables are routed through the self-sealing membranes, with the sealing range of 8.2 to 12.5 mm allowing adaptation to different cable diameters. Mounting can be done without additional tools, provided the fastening elements are available.

Advantages in Operation
The Mini 25-L offers a secure and tight installation thanks to the IP55 protection rating and self-sealing membranes. The use of halogen-free material increases safety in case of fire. The compact design and external mounting facilitate installation and adapt flexibly to various installation scenarios. The box is designed for standard indoor applications and can also be used outdoors, provided environmental conditions meet the IP55 protection rating. Dimensions of 89 × 43 × 38 mm allow placement in confined spaces without compromising functionality.
