It's built on the Size S0 frame and ships with one 3RT2023-1AK60 contactor pre-installed per direction of rotation. The 110 V AC 50 Hz / 120 V AC 60 Hz coil matches standard control voltages across 50/60 Hz plants. ## Mounting and wiring Snaps onto 35 mm DIN rail or screws directly to a backplate — the fastening method accepts both. Dimensions are 90 mm wide by 101 mm high by 97 mm deep — the S0 footprint is compact enough for high-density panels. Clearance around the assembly: 6 mm upwards, forwards, downwards, and sideways, with zero clearance needed backwards. ## Environmental limits and mechanical life The contactor typical mechanical life is 10 million operations; maximum electrical switching rate at AC-3 is 1,000 cycles per hour. Shock resistance: 11.8 g / 5 ms and 7.4 g / 10 ms on AC; 15 g / 5 ms and 10 g / 10 ms on DC. This matters for applications mounted on vibrating machinery or near impact loads — the assembly holds contact integrity within those limits.","metaTitle":"Siemens 3RA2323-8XB30-1AK6 SIRIUS Reversing Contactor","metaDescription":"Siemens SIRIUS 3RA2323-8XB30-1AK6 reversing contactor assembly, rated 4 kW at 400 V AC-3.
