| 2 | 180 | Frame current: 100=100A, 160=160A, 250=250A, 400=400A, 630=630A |
| 3 | 3 | Poteaux: 1=1P, 2=2P, 3=3P, 4=4P |
| 4 | EF | Trip + pouvoir de coupure: E=25kA, F=36kA, G=50kA, H=70kA, J=85kA; E=fixed thermal‑magnetic, F=adjustable thermal‑magnetic |
| 5 | 32 | Accessoire: 3=standard, 4=with auxiliary contact, 5=with shunt trip |
| 6 | 0AA0 | Special function: 0AA0=no diagnostics, 0AB0=with diagnostics |
