The auxiliary contact ratings are given for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V AC. These are the maximum continuous currents the auxiliary contacts can make and break at those voltages — useful for control-circuit isolation on a 24 VDC PLC output or a 230 VAC pilot lamp. The AC-2 rating of 30 kW at 400 V covers slip-ring motor starting, where the contactor closes on reduced current and opens at rated current. That means the total break time stays under about 34 ms — fast enough for most motor-protection coordination with upstream fuses or circuit breakers. The contactor measures 146 mm high, 70 mm wide, and 139 mm deep. The front is IP20 with the cover or box terminal installed; the terminal area itself is IP00, so keep live parts behind a panel door or cover during operation.","metaTitle":"Siemens 3RT1044-1AV60 SIRIUS Power Contactor, 37 kW at 500 V","metaDescription":"Siemens SIRIUS 3RT1044-1AV60 power contactor, size S3, 37 kW at 500 V, 55 A at AC-4 400 V.
