Why Use a Motor Overload Protector?
Motor overloads are a leading cause of premature compressor and fan motor failure. The Supco OV50 acts as a critical line of defense, interrupting power when current exceeds the 45–49 amp threshold — preventing insulation breakdown, winding burnout, and unplanned system downtime. Selecting the correct amp range ensures reliable trip response without nuisance tripping during normal motor startup.
