For across-the-line starting of standard squirrel-cage motors, the AC-3 capability is the relevant figure; the contactor handles 37 kW at 500 V and 18.6 kW at 690 V. AC-4 reversing or inching duty is rated 55 A at 400 V. Mechanical life is listed at 10 million cycles typical. At the maximum AC-3 switching rate of 1,000 operations per hour, that's over 10,000 hours of continuous cycling — realistic for a conveyor or pump duty that cycles every few seconds. ## Wiring and integration Main circuit terminals accept solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (10 to 50 mm²) — that covers control wiring through motor power cables up to roughly 70 A. The auxiliary contact block on the front (the 3AV60 variant) is wired separately via the same screw terminals. Dimensions are 70 mm wide, 146 mm high, 139 mm deep — the S3 frame.","metaTitle":"Siemens 3RT1044-3AV60 SIRIUS Power Contactor, 480 V 60 Hz, 3","metaDescription":"Siemens SIRIUS 3RT1044-3AV60 power contactor, Size S3. 480 V 60 Hz coil, 30 kW AC-2 at 400 V.

Electrically, only if the coil voltage matches: 3RT1044-3AV60 runs on 480 V 60 Hz, while 3RT1044-1FB46 uses a different coil. If the control circuit supplies 480 V 60 Hz, it's a direct swap."},{"question":"What compliance documentation does this brand provide for 3RT1044-3AV60?","answer":"The part carries a RoHS compliance date of 05/01/2012, indicating compliance with EU RoHS since that date.
