AutomationDirect SR22-FAN-55 Cooling Fan

SR22-FAN-55 is the Stellar SR22 series main cooling fan for AutomationDirect soft starters, designed to fit the 40 x 40 x 20 mm form factor and operate from 24 VDC. This accessory increases the SR22’s duty cycle to 60 starts per hour, helping manage thermal load when the soft starter is cycling frequently. It is used with SR22-22, SR22-30, SR22-36, and SR22-40 models, providing additional cooling for the SR22 assembly during high-start scenarios. By adding active cooling, the SR22-FAN-55 supports reliable operation in demanding 3-phase motor control applications and helps prevent thermal shutdown or performance throttling in environments where start frequency is high. The part is marketed as a main cooling fan specifically for the Stellar SR22 series, aligning with AutomationDirect’s Stellar line of soft starters. Typical installations include automation or machine-control cabinets where SR22 soft starters regulate motor start sequences, enabling a higher duty cycle without overheating.
