Nu-Calgon 5010-30 NuStart Compressor Soft Starter, Three Phase, 208/230VAC, 04-28A FLA/RLA

Description

NuStart is both a soft starter and protection device for scroll compressors in HVAC/R systems. NuStart uses current-based motor control to optimize motor start-up of the scroll compressor. In doing so, significant reductions inrush current and motor torque result. End-user benefits include: reduction in start-up noise and vibration, eliminates light flicker and nuisance circuit breaker trips at start-up, reduction in contactor arcing, and significant reduction in mechanical stress on the compressor, compressor mounts, and connected refrigerant piping at start-up. Lowering the inrush current of the compressor allows for more efficient start-up with off-grid solutions such as solar/battery systems or other back-up power sources – allows the use of a smaller generator.

NuStart provides another level of protection for the scroll compressor in the HVAC/R system. NuStart offers reverse motor (scroll) protection, plus under voltage protection to prevent motor stalling at start-up or during operation in low voltage (brownout) events, over voltage and reverse phase protections. The device is tolerant to “dirty power” conditions. NuStart provides additional compressor protection – it is NOT a replacement for any primary circuit breaker or an overload protection device, nor is it a surge protector.

Application:

NuStart is the premier solution to start and protect scroll compressors in the HVAC/R market. The OEM approved technology is the most trusted in the HVAC/R market – with years of global installations.

NuStart is the most compact device available allowing for the easiest installation inside the condensing unit. In addition, the device provides many advantages that other competing products don’t offer including: reverse scroll protection technology, hard start time out feature, and best market line-up with single and three phase options for residential and commercial systems.

Features:

• Most Compact Soft Starter in the Market
• Compatible with all Modern Scroll Technologies
• Reduces In-Rush Current by 30–50%
• Lowers Start-Up Torque by 50–70%
• Greatly Reduces Compressor and Refrigerant Piping Stress
• Reduces Start-Up Noise and Vibration
• Eliminates Light Flicker at System Start-Up
• Reverse Motor Protection
• Integrated Reverse Phase Protection
• Under Voltage and Over Voltage Protection
• Compatible with Major Utility Regulations
• Easy Retrofit

NuStart is designed for modern scroll compressor technologies in the HVAC/R market – single stage, dual stage, and digital type scroll compressors. Do NOT use NuStart for inverter type scroll compressors.

For other compressor types, contact Nu-Calgon.

NuStart must be selected on proper electrical phase, RLA, and LRA of the compressor stated on the nameplate of the condensing unit.

Use NuStart for the following systems equipped with scroll compressors:

Air Conditioning, Heat Pumps, Chillers, Refrigeration

NuStart model 5010-30 covers commercial air conditioning, heat pump, chiller, and refrigeration systems systems that operate on 230 VAC or 460 VAC three phase power. They are an excellent accessory to offer with new HVAC/R installs or systems already in service to optimize starting scroll compressors up to 20 horsepower.

Commercial compressors exhibit a significant amount of torque at start-up, typically generate significant noise and mechanical shock to the refrigerant piping often requiring vibration eliminators to protect the piping. NuStart reduces start-up torque by 50–70% thereby greatly reducing mechanical stress to the compressor, compressor mounts, and refrigerant piping. If the piping is not properly protected, ongoing stress to refrigerant piping could lead to a potential refrigerant leak and expensive repair. NuStart provides more latitude to operate the system off-grid or battery back-up power options with more efficient HVAC/R system start-up.
