It saves the panel builder from wiring three separate contactors and the interlock logic, cutting commissioning time on motor control centers. Rated at 7.5 kW at 400 V in AC-3 duty (17 A), it switches motor loads up to that current without contact welding during the transition. The 690 V rating of 9.2 kW covers the higher-voltage end, though the 400 V figure is what most European-line applications will reference. ## Mounting and integration — DIN rail, no side gaps needed Side-by-side mounting clearance is 0 mm, meaning you can butt multiple units directly without a cooling gap. The 135 mm width × 148 mm depth × 71 mm height footprint fits standard gland-plate layouts. The AC-3 rating at 400 V (17 A) is the figure that governs motor switching — it's the duty cycle for starting and disconnecting squirrel-cage motors under load. At 500 V it handles 10.3 kW, and at 690 V it drops to 9.2 kW (the voltage derating curve matters for variable-frequency drive outputs with long cable runs). Control supply is AC only, so if your panel runs 24 VDC control, this assembly needs an interposing relay or a different variant. The operating range covers most industrial environments, but derate above 40 °C per the thermal curve.","metaTitle":"Siemens 3RA1416-8XC31-1AP0-ZS02 SIRIUS Wye-Delta Contactor","metaDescription":"Siemens SIRIUS 3RA1416-8XC31-1AP0-ZS02 wye-delta contactor assembly.
