The Spelsberg Junction Box Enclosure (334-412) is designed for electrical contractors and DIY enthusiasts who require a reliable, compact solution for organizing and protecting wire connections. Its key benefit is the inclusion of 12 integrated strain-relief entry points and 5 screw terminals, which streamline installation and ensure secure cable management. However, potential users should note that the unit carries an IP20 rating, meaning it is intended for indoor, dry environments and is not waterproof or suitable for outdoor exposure.

No, this unit has an IP20 rating and is designed for indoor, dry use only.
The integrated terminals are designed for 2.5mm² conductors.
The box includes external fixing positions, but mounting screws are typically provided by the installer based on the surface material.
The unit measures 85mm x 85mm x 37mm.
Yes, it meets DIN EN 60670 (VDE 0606) standards.
The enclosure features 12 integrated entry points for flexible cable management.
Ensure the conductor is stripped to the proper length and the terminal screw is fully tightened against the metal core of the wire.
Check that no wires are protruding or obstructing the perimeter edges of the box, as these can prevent the lid from seating correctly.
Ensure all external fixing points are utilized and the screws used are appropriate for the substrate (wood, drywall, or masonry).
To install, select a flat, dry surface where the enclosure will not be exposed to moisture or extreme heat. Use the external fixing lugs to screw the base into your mounting surface. Ensure that cables are stripped to the appropriate length before inserting them into the screw terminals. Tighten terminals securely to prevent heating, but avoid over-tightening as this may strip the screw threads. Since the unit is rated IP20, periodically dust the interior if it is placed in an area that is not completely sealed. Avoid using liquid cleaners inside the box; if cleaning is necessary, ensure all power is disconnected and use a dry, soft brush or cloth.
