TRADEPRO Hard Start Kit [1/3 HP-2 HP] TP-5

Product Overview

The TRADEPRO TP-5 Hard Start Kit is a compact, high-performance solid-state hard start capacitor designed to give your compressor the extra torque it needs during startup. Ideal for single-phase air conditioners, heat pumps, and refrigeration units (typically 1/3 HP to 2 HP range), this kit helps overcome common starting issues caused by low voltage, long extension cords, high head pressure, or aging compressors.

Key Features

  • PTC Relay Technology: Uses a Positive Temperature Coefficient relay for fast, reliable engagement and automatic disengagement once the compressor reaches operating speed.
  • High-Quality Capacitor: Rated 43-53 µF with 277V maximum operating voltage for strong starting boost.
  • Easy Installation: Simple wiring with quick-connect terminals – installs in minutes on most single-phase compressors.
  • Compact & Durable: Lightweight aluminum construction, UL Recognized for safety and reliability.
  • Versatile Compatibility: Works with a wide range of residential and light commercial HVAC/R systems.

Benefits

  • Reduces Starting Amps: Significantly lowers inrush current (often by 30-50%), easing stress on the compressor and electrical system.
  • Extends Compressor Life: Minimizes wear from hard starts, helping prevent premature failure and costly replacements.
  • Improves Reliability in Tough Conditions: Perfect for low-voltage areas, high ambient temperatures, or units that struggle to start.
  • Energy Efficiency & Quieter Operation: Faster startups mean less strain on your electrical panel and reduced noise during ignition.
  • Cost-Effective Solution: A simple, affordable upgrade that can add years to your existing system’s lifespan.

Whether you’re a homeowner dealing with a sluggish AC unit or a technician servicing multiple systems, the TP-5 Hard Start Kit delivers dependable performance and peace of mind.

Key features
  • Compressor Hard Start Kit — for 1/3 to 2 HP compressors
  • Solid-State Design — compact, high-performance capacitor
  • Extra Startup Torque — helps compressors start reliably
  • Single-Phase AC Systems — TradePro TP-5
