The coil is wound for 200-240 V AC. ## What the AC-3 rating means for fit The AC-3 rating of 9 A and 4 kW at 400 V defines the contactor's capability for starting and stopping squirrel-cage motors under full load — the standard duty for a general-purpose motor contactor. The 200-240 V AC coil means the control circuit must supply that voltage range; a 24 V DC coil variant would be a different order code. The Size S0 footprint is the standard 45 mm width for this class, fitting a common DIN-rail slot.","metaTitle":"Siemens 3RT1023-1AM70-0KR0-ZW97 Power Contactor, AC-3 9 A, 4","metaDescription":"Siemens 3RT1023-1AM70-0KR0-ZW97 power contactor, AC-3 9 A, 4 kW / 400 V, 3-pole, Size S0, 200-240 V AC coil.
