Comparison with Siemens 3RT1034-1AP00:
| Feature | ABB AF26-30-00-14 | Siemens 3RT1034-1AP00 |
|---|---|---|
| Rated Current (AC-3) | 26 A (400V) | 40 A (400V) |
| Power (AC-3, 400V) | 11 kW | 15 kW |
| Coil Voltage | 230V AC (default) | Varies (check part no.) |
| Mounting | DIN rail/screw | DIN rail/screw |
Notes:
The AF26-30-00-14 is a smaller contactor compared to the Siemens 3RT1034-1AP00 (26A vs. 40A).
