Carrier 13B0045N05 Soft Start Kit 230V

The Carrier 13B0045N05 is an OEM Soft Start Kit designed for 230V Carrier HVAC systems. Soft start technology is a proven solution for reducing the high inrush current that occurs when a compressor motor starts, protecting your equipment and electrical infrastructure from the stress of repeated hard starts.

Why Use a Soft Start Kit?

During a standard compressor startup, the motor draws a surge of current that can be several times higher than its normal running amperage. Over time, these repeated high-current events cause premature wear on compressor windings, contactors, and capacitors. A soft start kit limits this inrush current, delivering a smoother, more controlled ramp-up to full operating speed.
