SPP5 Hard Start Capacitor Relay Nixes Compressor Grinding with Zero Stress Hookup Save Big Bucks Avoid an Appliance Guy Visit Fits 115 through 288 Volt Coolers

Hard Start Capacitor Relay Boosts Cooling Performance
✔️ 2-wire mount boosts startup torque 300% for coolers

This handy relay stops compressor grind by delivering instant surge power during ignition. You will slide it onto your rooftop cooling unit to skip costly service calls entirely.

✅ Direct two-wire connection attaches parallel to existing run capacitors
✅ Operates safely across 115 to 288 volt systems for single phase motors
✅ Handles cooling loads spanning four thousand to one hundred twenty thousand BTU ratings
✅ Internal solid state switch multiplies torque output by three hundred percent
✅ Durable housing passes rigorous quality checks before shipping

💡 Why does a vintage climate system struggle to engage the main refrigerant pump initially?
Massive thermal drops force older motors past safe current limits during cold starts.
- High inertia pistons resist immediate rotation without peak voltage injection
- Worn contactor gaps lose closure strength causing delayed power delivery
- Adding this boosting kit cuts startup amps sharply while extending overall lifespan
