What the 80 A AC-1 rating means for your load
The 3RF3380-3AA22 is a 1-pole SIRIUS 3RF33 solid-state contactor rated 80 A in AC-1 duty at 40 °C. AC-1 covers resistive loads — heaters, ovens, lighting banks — where the current waveform stays near sinusoidal with no motor inrush or inductive kickback. That 80 A figure is the continuous current the triac pair can carry in free air at the stated ambient; derate for higher enclosure temperatures or tight panel packing. The control circuit accepts a wide AC supply range of 24-230 V AC / 110-230 V AC, which simplifies stocking across sites with different control voltages.
Panel integration and connection
Termination is via ring cable lug — expect to crimp ring terminals onto the load and line cables rather than using fork or pin lugs. The 105 x 73 x 128 mm package (L x W x H) fits standard DIN-rail enclosures; account for the depth when routing cables behind the panel. No forced cooling required at the 80 A AC-1 rating, but maintain the manufacturer's minimum spacing to adjacent heat-generating devices.
