Solera neutral and protective distribution blocks: connection layouts

Solera connection blocks include neutral and protective blocks and references combining terminals of different capacities. This category lists 212N and 212TT alongside the 105, 113, 180 and 128 families and combined 113PE/N block. Select by function, connection count, permitted conductor section and mounting compatibility.

Reference comparison

Reference	Format / layout	Section / dimension	Declared data
212N / 212TT	12 x 6 mm² + 2 x 16 mm²	—	76A
105N / 105PE	5 x 6 mm²	—	41A
113N / 113PE	13 x 6 mm² + 4 x 16 mm²	—	76A
180N / 180PE	18 x 6 mm² + 6 x 16 mm²	—	76A
128N / 128PE	28 x 6 mm² + 6 x 16 mm²	—	76A
113PE/N	PE (13 × 6 mm² + 4 × 16 mm²) + N (13 × 6 mm² + 4 × 16 mm²)	—	76A

Selection and installation

Do not confuse connection count with conductor section: N28 or T28 does not mean 28 mm². Check the internal layout, section ranges and fixing and tightening instructions. Neutral and protective conductors have different functions; retain their identification and separation according to the circuit diagram. A distribution block alone does not determine protection selectivity.

Respect electrical limits and the instructions for the reference and receiving equipment. Disconnect the supply before making connections; nominal section alone does not validate the assembly.

Frequently asked questions

Do 128N and 128PE accept 28 mm² cable?

The number 28 identifies the family’s connection layout, not a 28 mm² conductor section. Check the conductor range accepted by the terminals in the sheet.

How are 212N and 212TT configured?

Each lists 12 terminals up to 6 mm² and 2 up to 16 mm². 212N is identified for neutral and 212TT for earth; check their diagram and mounting.

Does 113PE/N mean neutral and protection should be joined?

It combines identified PE and N groups. That does not mean they should be bridged: follow the circuit diagram and required separation.
