Insulated pin busbar
Insulated busbars: safe and orderly power distribution between modular protection devices.
- Configurations: 1P, 2P, 3P and 4P solutions.
- Sections: 10mm² and 16mm² according to current requirement.
- Lengths: 216mm and 1m options for flexible assembly.
- Safety: end caps for protected busbar termination.
Connection busbars for power distribution in modular panels
Solera connection busbars distribute the supply between compatible modular devices and organise repeated connections within a panel. The family includes seven busbars in 1-, 2-, 3- and 4-pole formats, plus four end-cap references. They are intended for indoor residential and commercial installations such as homes, offices and shops. A busbar distributes current; it does not replace circuit breakers or other circuit protection.

Choosing a busbar and completing its ends
The 10 mm² formats in this table are rated at 63 A; the 16 mm² formats at 80 A. P2P21610 is 216 mm long with a grouping of 6 × 2 modules. P2P100010 and P2P100016 share a 1 m, two-pole format with 28 × 2 modules but differ in cross-section and rated current. The module grouping is the value stated in each product data sheet; it does not by itself guarantee connection to any arrangement of devices.
Before selection, check pole count, phase and neutral sequence in the assembly, device width, terminal spacing and alignment, connection geometry and whether the device terminal accepts the busbar connection. The two- and four-pole model descriptions specify pin-type connection. Matching pole counts or mounting on a DIN rail does not establish universal compatibility across brands or series.
The busbar data sheets specify 230/400 V AC, 50/60 Hz and an operating temperature of −5 to +40 °C. Size the supply and protection for the expected current and assembly conditions, including the feed point. The 63 A or 80 A rating is not independently available at every pin and does not allow other component ratings to be exceeded.
TAPA-1P, TAPA-2P, TAPA-3P and TAPA-4P are white end caps for one-, two-, three- and four-pole busbars respectively; their descriptions specify bags of 10 units. They are separate accessories: check the supplied items and fit with the particular profile. Qualified personnel must install the assembly with power disconnected, following the device and assembly instructions.
Frequently asked questions
Will a two-pole busbar fit any two-pole device?
Pole count alone is insufficient. Terminal spacing, alignment, geometry and position must match, together with the electrical arrangement of the assembly. Also check that the device manufacturer allows the busbar connection; similar modular width does not establish compatibility.
When should I choose 10 mm² rather than 16 mm²?
Compare the design current with the complete assembly ratings. For the published references, 10 mm² corresponds to 63 A and 16 mm² to 80 A. A larger cross-section does not automatically increase the permissible current of the panel, its terminals, protective devices or supply.
Can I cut a 1 m busbar and use any end cap?
First check whether the reference and its instructions allow cutting and specify how to do it. Where permitted, the ends must be properly finished and insulated with a cap matching the pole count and profile. Do not assume the cap is included or infer an assembly IP rating from it.
