Screw terminals on the main circuit accept up to 2x 10 mm² or a single 10 AWG, so it'll handle the wire sizes you typically run for a 11 kW motor at 400 V.
Ratings that matter for motor switching
AC-4 at 400 V is 15.5 A, covering reversing or inching duty where you're switching stalled rotor currents.
Built-in surge suppression and aux contacts
This variant comes with an integrated RC surge suppressor across the coil — no separate suppressor module to buy and mount. The two instantaneous auxiliary contacts handle 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, which is enough to signal a PLC input or drop out a holding circuit.
What approvals and documentation to expect
This contactor carries the usual SIRIUS compliance suite: IEC/EN 60947-4-1 for contactors and motor starters, UL/CSA pending the specific variant suffix. The RC suppressor means it meets EMC emission limits without external filtering. Declaration of conformity and RoHS/REACH documentation are available from the manufacturer's support portal.
