Square D LC2D09REQ3827G13 Reversing Contactor, 575VAC 9A, IE

The 575VAC 9A rating is the IEC utilization category current at that voltage — typically AC-3 for motor reversing duty. That means it handles a 3-phase induction motor up to about 4 kW at 575V, switching the load under full current. The reversing interlock is mechanical, so the contactor set prevents both coils from pulling in simultaneously. The IEC special designation often covers a specific coil voltage or termination variant not in the standard catalog; check the coil marking on the unit you receive against your control voltage.
