Part identity and lifecycle status
The 3RT5044-1AN20: Rated insulation voltage is 1000 V, with an AC-3e maximum rating at 1000 V, making it suitable for switching three-phase motor loads up to that voltage class in industrial control panels.
Mounting and integration
Mounts via screw or snap-on onto 35 mm and 75 mm DIN rail, with mounting position flexibility: ±180° rotation on a vertical surface, and ±22.5° tilt forward/backward. Side-by-side mounting is permitted, which simplifies dense panel layouts. The S3 frame occupies 70 mm width and 146 mm height, with a depth of 139 mm. Main circuit connections accept screw-type terminals for 2x (2.5 to 16 mm²) solid or stranded wire, or 2x (10 to 1/0 AWG).
Switching performance and ratings
Rated for 5000 operating cycles per hour at AC, with maximum rates of 1000 cycles/h for AC-1, AC-3, and AC-3e duty, and 300 cycles/h for AC-4. The AC-3e rating at 1000 V is the headline motor-switching capability — this contactor handles motor starts and stops within that voltage and duty cycle without derating. Coil draw at 24 V is 6 A; at 110 V it drops to 1 A, and at 220/230 V to 0.3 A. The coil is rated for both 50 Hz and 60 Hz operation at 220 V with a power factor of 0.27. Power-switching capability at 60 °C ambient: 34 kW at 230 V, 59 kW at 400 V, and 102 kW at 690 V. The contactor is rated for pollution degree 3, meaning it tolerates conductive pollution typical in industrial environments.
Compliance and environmental
RoHS compliant with a substance prohibition date of 03/01/2017. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The mechanical endurance is rated at 10,000,000 operating cycles typical.
