Cable splices
Enclose a joint between two cable runs.
Junction Boxes / product groups
Junction boxes for cable splices and power branches.
Protect a cable joint, add a branch or bring several cables into one box. Choose compact F1 boxes, an F2 T-junction, F3 multi-way boxes or the larger F5 range.

Junction Boxes product groups
Choose a box for the number and direction of cables.
F1 boxes have two to four entries, F2 provides a three-way T layout, F3 spans two to six ways, and F5 spans three to eight ways. A separate enclosure houses a rocker switch.
F1 Mini Junction BoxesCompact junction boxes with two, three or four cable entries for enclosed cable joins.Choose two, three or four entries to suit the cable route and available mounting space.
F2 T-Junction BoxesThe F2-3T box provides three cable entries in a T layout for branch connections.Use the three-port T layout for a branch connection, with terminals sized for the conductors.
F3 Multi-Way Junction BoxesTwo- to six-way junction boxes for joining cables or connecting several branches.Choose two to six entries, then match the terminal and cable size at each port.
F5 High-Power Junction BoxesLarger junction boxes with three, four, five, six or eight cable entries for power distribution.Choose three to eight entries and terminal capacity for the distribution circuit.
Switch EnclosuresA compact housing for a rocker switch with a 22 × 31 mm opening. The switch is not included.Choose a rocker switch that fits the 22 × 31 mm opening and the available wiring space.Selection guide
Match the cable entries and terminal capacity.
Count the cables and note where each will enter. Leave room for the terminals, conductor bends and access to the cover.

Junction Boxes FAQ
Product selection questions
Find answers about the differences between product types and how to choose a model.
01How do F1, F2, F3 and F5 boxes differ?
F1 offers compact two- to four-way boxes. F2 is a three-way T box. F3 offers two to six ways, while the larger F5 range offers three to eight. Compare terminal capacity and cable range as well as entry count.
02Does the number of entries tell me how the box is wired?
No. Cable entries describe the housing layout. The terminal arrangement determines which conductors connect, so use the wiring layout to choose the box.
03What can I send if I do not know the box model?
Send a photo or sketch of the cable layout. If available, add the cable diameters and conductor sizes so we can help narrow the options.
