Nu-Calgon 5010-21 Nustart Compressor Soft Starter-16-32 RLA-1 Phase-208/230 VAC for Scroll Compressors

NuStart is both a soft starter and protection device for the scroll compressor in the HVAC/R system. The product uses a current-based motor control to optimize motor start-up for the scroll compressor, in doing so, significant reductions in-rush amperage and motor torque with compressor start-up. End-user benefits include: reduction in start-up noise and vibration, eliminates light flicker and nuisance circuit breaker trips, reduction in contactor arcing, and less mechanical stress on the compressor and connected refrigerant piping. Furthermore, lowering the in-rush current of the compressor allows for a more efficient start-up with off-grid solutions such as solar/battery systems or backup power sources, allowing the use of a smaller generator. NuStart provides another level of protection for the scroll compressor in the HVAC/R system. NuStart offers exclusive reverse motor (scroll) protection and under voltage protection to prevent motor stalling at start-up or during operation in low voltage (brownout) events. The single-phase series provides overcurrent protection to the compressor, whereas the three-phase types provide overvoltage protection and reverse motor detection features. NuStart provides added protection to the compressor – it is NOT a replacement for any primary circuit breaker or an overload protection device.

• *NuStart must be selected on proper electrical phase, RLA, and LRA of the compressor stated on the nameplate of the condensing unit. Do not use this item on a unit with RLA outside the 16-32 range.* FOR PROFESSIONAL INSTALLATION ONLY
