16 32A AC Soft Starter with Reverse Motor Protection for 4 7 Ton Install Kit

This AC Soft Starter with Reverse Motor Protection is an electronic motor starter that limits compressor inrush current and prevents damage from reverse rotation, designed for 4-7 ton air conditioning installation kits.

Product Overview

The 16-32A AC Soft Starter reduces the startup surge of single-phase air conditioning compressors rated 4-7 tons, protecting electrical systems and extending compressor life. Its built-in reverse motor protection circuit instantly detects and corrects phase reversal, safeguarding the compressor against mechanical failure. Ideal for HVAC contractors and installers performing new AC system setups or upgrades.

Key Features & Performance

• Adjustable current range of 16A to 32A accommodates 4-ton through 7-ton AC compressors.
• Ramp-up soft start reduces inrush current by up to 70%, preventing light flicker and breaker trips.
• Reverse motor protection automatically halts and corrects incorrect rotation before compressor damage occurs.
• Microprocessor-controlled timing and voltage sensing provide consistent and reliable starting cycles.
• Compact design mounts directly inside the electrical disconnect box or nearby enclosure.
• Supports single-phase 208-240V systems, compatible with most residential and light commercial AC units.

Fitment & Compatibility

• 4-ton, 5-ton, 6-ton, and 7-ton air conditioning and heat pump compressor systems.
• Installation kits for ducted split systems and package units with single-phase compressors up to 32A rated load.
• Suitable for both new installations and retrofits where reduced startup current is required.

Common Uses

• Reducing electrical load on portable generators when running RV or home AC units.
• Eliminating light flicker in homes with weak utility service during compressor startup.
• Retrofitting older AC systems to meet energy code requirements for soft starting.
• Installing in tandem with hard start kits for compressors in high-elevation or cold-climate applications.
• Protecting inverter-driven appliances from voltage sags caused by large compressor surges.

Frequently Asked Questions

Q: Can this soft starter be used with a 3-ton air conditioner? A: This unit is optimized for 4-7 ton compressors; using it on a smaller 3-ton system may result in incomplete starting or nuisance tripping.

Q: Does the reverse motor protection work after installation or only during startup? A: The protection continuously monitors rotation direction after startup and will interrupt power if reverse rotation is detected at any time.
