It is rated for 15 kW in AC-2 duty at 400 V, which covers wound-rotor motor applications, and 29 A in AC-4 duty at 400 V for plugging and inching of squirrel-cage motors.
These are the ratings that govern real-world fit, not a generic thermal current. Mechanical life is rated at 10,000,000 operations typical, with maximum switching frequencies varying by duty: 1,200 cycles per hour at AC-1, 750 at AC-2, 1,000 at AC-3, and 250 at AC-4. The contactor can be mounted side-by-side without derating, which simplifies panel layout.
Main circuit terminals accept solid conductors from 2x 0.25 to 2.5 mm² and stranded conductors from 2x 0.75 to 25 mm². The minimum permissible conductor cross-section at 40 °C is 16 mm². Auxiliary and control circuit wiring uses the same screw-clamp technology. Dimensions are 55 mm wide, 112 mm high, and 164 mm deep — the depth is the dimension that extends behind the DIN rail, so verify cabinet depth clearance before specifying.
No other compliance documents (UL, CSA, CE) are listed in the spec record, but the SIRIUS family typically carries these; verify the specific nameplate marking for your jurisdiction.
