Please refer to the product description or manufacturer documentation for included items.
The Nu-Calgon NuStart Soft Starter (Model 5010-20) is a compressor start-assist and protection device engineered for HVAC/R scroll compressors. NuStart uses advanced current-based motor control to optimize compressor start-up, significantly reducing inrush current and torque during start, which lowers stress on the motor and electrical components. This leads to reduced start-up noise, fewer nuisance breaker trips, minimized contactor arcing, and improved long-term compressor reliability. NuStart also offers built-in protections including reverse scroll motor protection, under-voltage shutdown, and overcurrent limit features. Designed for single phase residential and light commercial A/C and heat pump systems operating on 208-230 VAC, Model 5010-20 helps extend compressor life and supports efficient, reliable system operation.
