1.1 Main Product Series
Siemens MCCBs mainly include the 3VA series (new generation) and 3VL/3VT series (legacy). The 3VA series covers frame currents from 100A to 1600A, divided into 3VA1 (thermal-magnetic trip) and 3VA2 (electronic trip) sub-series.
1.2 3VA Series Naming Rule (Example: 3VA1180-3EF32-0AA0)
| Segment | Code | Meaning |
| 1 | 3VA1 | Series: 3VA1 = thermal‑magnetic, 3VA2 = electronic trip |
| 2 | 180 | Frame current: 100=100A, 160=160A, 250=250A, 400=400A, 630=630A |
| 3 | 3 | Poles: 1=1P, 2=2P, 3=3P, 4=4P |
| 4 | EF | Trip + breaking capacity: E=25kA, F=36kA, G=50kA, H=70kA, J=85kA; E=fixed thermal‑magnetic, F=adjustable thermal‑magnetic |
| 5 | 32 | Accessory: 3=standard, 4=with auxiliary contact, 5=with shunt trip |
| 6 | 0AA0 | Special function: 0AA0=no diagnostics, 0AB0=with diagnostics |
